Answer:
The speed of the cyclist is 2.75 km/min.
Explanation:
Given
To determine
We need to find the speed of a cyclist.
In order to determine the speed of a cyclist, all we need to do is to divide the distance covered by a cyclist by the time taken to cover the distance.
Using the formula involving speed, time, and distance

where
substitute d = 88, and t = 32 in the formula


Cancel the common factor 8

km/min
Therefore, the speed of the cyclist is 2.75 km/min.

Given,
Displacement of the car = 150 km
Velocity of the car = 15.0 km/h
We need to calculate the travel time t
We all know that the formula to calculate velocity is
Velocity = displacement / time
From the above equation,
Time = Displacement / Velocity
Substituting the values in the above equation,
Time = 150 / 15.0 = 10 hours
Therefore, travel time = 10 hours.
