Question
A motorist travelled the distance between two towns, which is 65 km, in 2 hours and 10 minutes. Find his speed in metre per minute.
Solution
Distance between two towns = 65 km
Time taken = 2 hr 10 min
= `2 10/60=2 1/6=13/6`hrs
∴ Speed = `"Distance"/"Time"`
= `65/(13/6)`
= `(65xx6)/13`km/h
= 30 km/h
and speed in m/minute = `(30xx1000)/60`
= 500 m/minute
