Question

A motorist travelled the distance between two towns, which is 65 km, in 2 hours and 10 minutes.
Find his speed in meters per minute.

Answer 1

Given: a motorist travels a distance of 65 kms, in 2 hours and 10 minutes.

Distance $=65km$
$=65\times 1000m$ [$1km=1000meters]$
$=65000m$
Time $=$ 2 hours 10 minutes
$=$ 2 hours 10 minutes
$=2\times$ 60 minutes + 10 minutes
$[1hour=60minutes]$
$=130$ minutes

$\because Speed=\frac{distance}{time}$
$=\frac{65000m}{130time}$
$=500m/min$

Hence the speed of a motorist is 500 m/min.
