Question

find the total distance covered by a car in 20 minutes that moves with a non uniform speed of 50 kilometre per hour for the first 10 minutes and then with the speed of 60 km per hour for next 10 minutes​

Answer 1

Answer:

18.3km

Explanation:

First half:

speed*time=distance

50*10/60=8.30km {Since time is in minutes and speed in km/h}

Second half:

speed*time=distance

60*10/60=10km

8.3+10=18.3km
