Question

4.A train travels a distance of 20km in the first hour and 10km in the third hour. Calculate the average speed of the train.

Answer 1

Answer:

10km/hr

Explanation:

total distance travelled by the train = 20+10=30km

total time taken by the train = 3 hours

average speed of the train = total ditance/time

= 30/3 = 10km/hr

Answer 2

Answer:

Hence the average speed of train is 20 km / h

Explanation:

Train travel in first hour = 20 km

distance covered in second hour = 30 km

Distance covered in third hour = 10 km

Average speed = Total distance covered/ total time

=> 20+30+10/3

=> 60/3

=> 20 km/h

Hence the average speed of train is 20 km / h
