Question

A car moves at the speed of 20 km/hfor 15 minuetes and than at the speed of 60 km/h for 15 minuetes . Calculate the total distance covered by a car

Answer 1

Speed =distance / time

1.) 15 mins= 0.25hr

•20=d/0.25

•d = 20*0.25

•d = 5km

2.)15 mins= 0.25hr

•60=d/0.25

•d = 60*0.25

•d = 15km

Total distance = 15+5

=20
