Question

A train travels first 1000 kms at an average rate of 140 kmph and further travels the same distance at an average rate of 90 kmph. Determine the average speed of the train over the whole journey.

Answer 1

For the first 1000kms.

Average speed = 140 kmph.

Time taken to cover the distance = ( Distance / Speed )

Distance=1000km

For the next 1000 kms.

Average speed = 90 kmph.

Time taken to cover the distance = ( Distance / Speed )

Average speed for the journey = ( Total distance / Total time ) =  GIVES UR ANSWER
