Question

A bus travels at v km per hour. It is going from Daspur to Beespur. After the bus has travelled 5 hours, Beespur is still 20 km away. What is the distance between Daspur to Beespur? Express it using v.

Answer 1

Hint: A bus travels for 5 hours at a speed of v km per hour. Thus, the bus travels 5v km in 5 hours. After that, Beespur is still 20 km away. So, by adding both values, we can find the correct answer for it.

Complete step-by-step answer:
It is given that a bus is travelling at v km per hour speed from Daspur to Beespur.
Now, the bus has travelled 5 hours.
The distance travelled by bus in an hour is v km.
So, the distance travelled by bus in 5 hours is 5v km.
Still Beespur is 20 km away from there.
So, on adding the distance left to travel and the distance travelled by bus in 5 hours, we will get the distance between Daspur and Beespur.
Therefore, Daspur and Beespur are \[5v + 20\] km away from each other.

Note: The given question is connected with the concept of ‘speed’. The definition of the speed can be given as follows:
“speed word refers to the total distance covered and the time taken to cover that particular distance.”
Hence, \[speed = \dfrac{{dis\tan ce}}{{Time}}\]
