Question

A walker covers a disatance of 4.0 km in a time of 53 minutes. (a) What is the average speed of the walker for this distance in km/hr?

Answer 1

Average speed, v = 48.01 km/h

Step-by-step explanation:

Given that,

Distance covered by the walker, d = 4 km

Tim taken to cover that distance, t = 53 min = 0.0833 hours

We need to find the average speed of the walker for this distance. It is given by :

`speed=(distance)/(time)`

`speed=(4\ km)/(0.0833\ h)`

Speed, v = 48.01 km/h

So, the average speed of the walker is 48.01 km/h. Hence, this is the required solution.
