Question

9. A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. Thetotal distance covered by the car is :
​

Answer 1

Answer:

as speed = distance/time

so distance = speed * time

so distance by car 1 = 40*15

=60*15

=400

distance travelled by car 2=60*15

=900

total distance = distance of car 1 + car 2

=400+900

=1300km/h
