To find out the cyclist's average speed you simply have to divide 50.0km
by 2.5 to find the answer. Therefore the cyclist's average speed is
20.0 km an hour.
Answer is 20.0 km per hour.
Explanation;
S = d/t
Where, S is the speed, d is the distance and t is the time taken.
Here,
d = 50.0 km
t = 2.5 hours
By applying the formula,
S = 50.0 km / 2.5 hours
= 20.0 km per hour
Hence, the average speed of the cyclist is 20.0 km per hour.
