A jogger runs a mile in 8.92 minutes. 1 mi=1609m; calculate her speed in km/hr

Explanation:

Given

Distance = 1 mile

Time = 8.92 minutes

Required

Calculate Speed in km/hr

Substitute 1 mile for distance and 8.92 minutes for time

Convert Miles to Kilometres

If

;

Then

--- (1)

Convert minutes to hour

Multiply both sides by 8.92

---- (2)

By substituting (1) and (2) in , we have

-- Approximated
