Question

A car moves with a speed of 35 km/h for 5 min and then with speed of 50 km/h for n
ext 5 min . Find the total distance

Answer 1

Here we go,  

0.5hrs * 60mins = 30 mins

0.26 hrs * 60 mins = 15.6 mins

0.76 hrs * 60 mins = 45.6 mins

(50/60)*30=25kmph

(30/60)*15.6=7.8kmph

(70/60)*45.6=53.2kmph

25+7.8+53.2=86kmph

86/3=28.6 kmph average
