Question

A cross-country skier can complete a 7.5km race in 45min. What is the skiers average speed?

Answer 1

answer is 10km . i know its right

Answer 2

Average speed, v = 2.77 m/s

Step-by-step explanation:

It is given that,

Distance to be covered in a race, d = 7.5 km = 7500 m

Time taken, t = 45 min = 2700 sec

We need to find the average speed of the skier. It can be calculated as :

`v=(d)/(t)`

`v=(7500\ m)/(2700\ s)`

v = 2.77 m/s

So, the skiers average speed of 2.77 m/s. Hence, this is the required solution.
