A bicyclist travels 60.0 kilometers in 3.5 hours. What is the cyclist's average speed? Note: Average speed is the total distance divided by the total time taken.

The average speed of the cyclist is 17.14 km/hr

Explanation:

Given;

total distance traveled by the cyclist's, d = 60 km

time taken by the cyclist, t = 3.5 hours

The average speed of the cyclist is given by;

average speed  = total distance traveled / total time taken

average speed = 60 km / 3.5 hr

average speed  = 17.14 km/hr

Therefore, the average speed of the cyclist is 17.14 km/hr
