Question

A car travels with a speed of 55 km/h.How much distance will it cover in 2 hr 12 min

Answer 1

Car covers 55 km in 1 hr

So it covers 55×2 km in 2 hrs

i.e. 110 km

1 min =1/60 hr

12 min= 1/60×12= 0.2 hr

Car covers distance in 0.2 hr= 55×0.2

=11 km

By adding distance covered by car in 2 hr and 0.2 hr( 12 min) we will get total distance

So, 110+11=121 km is correct answer

Hope! You will find it easy and clear.
