Question

Train moves in average speed of 100 km/h, carrying a 10.000 KG load in each of the 55 freight cars. How long will it take for the train to reach Mombasa, if the distance is 500 km?

Answer 1

Answer:

Step-by-step explanation:

This is a simple question on linear motion.

The necessary formula is as follows.

Speed = Distance /time

Time = Distance / speed

In this question we have :

The speed of the train and the total distance to be covered.

The speed = 100 km/h

Distance = 500km

We need the time taken to travel this distance.

Time = 500/100 = 5

This time is in hours.

Therefore , time taken equals to 5 hours

Answer 2

Answer:

In this question, weight/ load carried by the freight car does not affect he time, since the concept of average speed is considered.

Hence, the use of simple formula involving average speed, time and distance will be considered.

We know that, Average speed = Total distance/ Total time taken

Therefore, 100 = 500/ total time taken

Therefore, total time taken = 500/100 = 5 hours.

Hence , the time taken will be 5 hours.
