Answer 1

Answer:

answer is 20

Explanation:

distance=1440km

time=12hr

speed=distance÷time

speed=1440÷12

speed=20

Answer 2

Given,

The distance travelled by a train = 1440 km

Time taken by the train to travel = 12 hours

Let, the speed of the train be x

Since , Speed = Distance/ Time taken

x = 1440/12

x = 120

So, the speed of the train will be 120 km/ hr
