Question

If you travel 105 miles at 70 mph, how long will the trip take?

Answer 1

Hint: In this question, we have to find the time taken in the trip if I travel 105 miles at 70 mph or miles per hour. For solving this type of question, we should know about the relations between speed, distance, and time. Then, we can solve this question easily.

Complete step by step answer:
So, let us solve the question now.
It is given in the question that if I travel 105 miles at 70 mph or miles per hour, then much time is going to take to complete the trip.
From here, we get that
Distance= d =105 miles
Speed = s =70 mph = 70 m/h
As we know the relation between distance, speed and time is \[s=\dfrac{d}{t}\] where s is the speed during the trip, d is the distance covered in the trip and t is the time taken during the trip to cover the distance d at a speed of s.
Hence, speed = distance/time
\[\Rightarrow \] time = distance/speed
\[\Rightarrow \] time = 105/70
If we calculate the above value then we will get the time as 1.5 and its unit is an hour.
Therefore, if I travel 105 miles at 70 mph, then the trip will take 1.5 hours.

Note:
If we just see the units of speed, distance, and time then just from there, we can get the formula of the speed, distance, and time.
Miles per hour= miles/hour
Therefore, speed = distance/time
The above equation also can be written as time = distance/speed.
In this type of question, the solving process is very easy as we just have to divide the two numbers.
