Question

a car travels a certain distance with a speed of 60km/h in 15min and then the remaining distance at a speed of 90km/h in next 15min calculate the total distance covered by the car​

Answer 1

Answer:

60km in 1 hour

Then car covers 15km in 15 minutes

If car covered 90km in 1 hour for remaining distance, then it covered 22.5km in 15 minutes.

So 15+22.5= 37.5km

Therefore, Total distance covered by car is 37.5km.

Hope it helps

Thank you
