Answer:
The speed of the cyclist is 2.75 km/min.
Explanation:
Given
- The distance d = 88 km
- Time t = 32 minutes
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
- s = speed
- d = distance covered
- t = time taken
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.
