5. Delhi- Mumbai (124772)

a) 1400km b) 1189 km c) 18h30min d) 76.50km/h

Explanation:

Speed = Distance/Time.

Speed describes the distance travelled divided by the time required to cover the distance and indicates how quickly or slowly an object goes.

According to the formula above, Speed is inversely proportional to Time and directly proportional to Distance.

Data of any five trains starting from Delhi and going to different states in India is listed below:

1) Delhi-Lucknow (82502)

a) Distance covered = 512 km

b) Displacement measured using atlas = 431 km

c) Average time taken to reach the destination = 6h25min

d) Average speed of the train = distance / time

                                               = 512/6.25

                                               = 81.92km/h

2) Delhi-Jaipur (22995)

a) Distance covered = 307 km

b) Displacement measured using atlas = 254 km

c) Average time taken to reach the destination = 5h5min

d) Average speed of the train = distance / time

                                               = 307/5.05

                                               = 60.79km/h

3) Delhi-Bhopal (12156)

a) Distance covered = 695 km

b) Displacement measured using atlas = 605 km

c) Average time taken to reach the destination = 9h

d) Average speed of the train = distance / time

                                               = 695/9

                                               = 77.22km/h

4) Delhi- Patna(20802)

a) Distance covered = 998 km

b) Displacement measured using atlas = 850 km

c) Average time taken to reach the destination = 15h35min

d) Average speed of the train = distance / time

                                               = 998/15.35

                                               = 65.01km/h

5) Delhi- Mumbai (124772)

a) Distance covered = 1400 km

b) Displacement measured using atlas = 1189 km

c) Average time taken to reach the destination = 18h30min

d) Average speed of the train = distance / time

                                               = 1400/18.30

                                               = 76.50km/h
