Question

A truck travels with a speed of 40km/for 30 min and then with a speed of of 30km/hfor 1hour.Calculate total distance travelled and averge speed of truck

Answer 1

Distance travelled in the first 30 min = 20km

Distance travelled in the next 1 hour = 30km

Hence, total distance travelled = 20 + 30 = 50 km

Then, average speed of the truck = distance/time = 50km/90min = 50000/5400 m/s = 9.26 m/s

HOPE THIS COULD HELP!!!
