A Trip to Bhopal Class 4 Notes CBSE Maths Chapter 3 [Free PDF Download]

Time

• The period in which something happens is called time. 

• Time is measured in hours, minutes, or seconds.

• We have seen a clock in our homes, it has 2 hands hour hand and a minute hand.

• Time can be represented as 1:00:00 am or 1:00:00 pm.

Time

• Here, hh represents the hour, mm represents minutes, and ss represents seconds.

• Example: Tina wakes up at 7:00:00 am. Get ready and finish her breakfast by 7:45:04 am. And goes to school at 8:00:15 am. In the example, everything that is bold tells about time. 

Sequence of Events

• If the things or events happen continuously like in the above example then it is considered to be a sequence of events. 

• We have 24 hours in a day, 60 minutes in an hour and 60 seconds in a minute.

• The clock includes numbers from 1 to 12. And when the minute hand that is the bigger hand is moved from ‘1’ to ‘2’ we say that 5 minutes have been completed.

• This means that when the minute clock moves to the next number we can add “5” to find the time.

Sequence of time

Solved Example 1: The students are going on a trip to Bhopal. They left at place ‘A’ at 8:15 am. If it takes 2 hours to reach Bhopal, then at what time do they reach Bhopal?

Ans: Given, Students left at 8:15 am. And it will take 2 hours to reach Bhopal.

So, if we add 2 hours to 8:15, we will get the final time.

We can represent one hour as 1:00:00 and 8:15 am as 8:15:00 am

1:00:00 + 8:15:00 am = 9:15:00 am

If we add one more hour, we get the final time as

   9:15:00 am + 1:00:00

= 10:15:00 am

Distance

• The length between two points is called distance.

• The distance can be measured in terms of meters, centimetres or kilometres.

Distance between two people is 2m

Units of Distance:

Solved example 1: Convert the following

a. 25 m = ? cm

Ans: From the above table we know that 1 m = 100 cm. Hence 25 m will be 25 multiplied by 100 cm,

25 × 100 = 2500 cm

b. 2 km = ? m

Ans: From the above table we know that 1 km = 1000 m. Hence 2 km will be 2 multiplied by 1000 m,

2 ×1000 = 2000 m

Solved example 2: On the way to the trip, the students found the flowing Narmada river under the bridge. If the river is 800 m wide, then the bridge will be 500 metres. Convert 500 metres into kilometres.

Ans: We know that 1 km = 1000 m if we divide 1000 by 2, then the result will be 500. This means that 

1km=100m/2=500m

We can rewrite it as,

1km=1/2× 1000m =500m

This means that half of a kilometre is 500 metres.

Hence we can write 500 m as half a kilometre.

Solved example 3: Suppose you are going for a trip, there you found a bridge. If we can keep 25 buses in a line on the bridge, then the length of the bridge will be? (Hint: length of 1 bus = 15 metres)

Ans: As per the question we can align 25 buses in a line, and 1 bus = 15 m.

Hence 25 multiplied by 15 gives us the length of the bridge.

25×15 = 375 metres.

Price

• The value that is given to a thing is called price.

• We can pay price in terms of rupees, dollars, cents, etc based on the country we are living in.

Solved examples: Use the table below to answer the questions:

Solved example 1: If 2 students choose Paddle-boat, then what is the total price paid by students?

Ans: From the given data, 2 students choose a Paddle-boat. And the price for boating is 15 rupees. Hence the total price will be the number of students multiplied by 15.

2×15 = 30 rupees

Solved example 2: Five of the students choose a Double-decker boat, what is the total trip time spent by them?

Ans: From the table of Price-list it is mentioned that the students who choose a Double-decker boat can spend 45 minutes. Hence from the above-given data, 5 students chose a Double-decker boat and spent 45 minutes enjoying the boating.

Practise Questions

1. Convert the following

a) 60 m = ? cm

b) 5 km = ? m

2. Tina went shopping and bought 2 shirts, a pair of pants, and 1 pair of earrings. She paid 450 rupees for 2 shirts, 600 for a pant, and 150 for a pair of earrings. What is the total price paid by Tina?

Ans 1: a. 6000 cm

 b. 5000 m

Ans 2: 1,200 rupees
