Question

A man takes a flight from Mumbai at 8.00 a.m. and reaches Delhi at 10.30 a.m.
If the distance between Mumbai and Delhi is 1440 km, calculate the speed of the
plane in m/s and km/h.​

Answer 1

Answer:

Explanation:

time of departure = 8:00 am

time of arrival= 10:30 am

total time taken to complete the journey = 10:30 - 8:00

                                                                    = 2 hrs 30 min

                                                                    = (150 x 60) sec or 2.5 hrs

                                                                    = 9000 sec or 2.5 hrs

distance = 1440 km

              = 14,40,000 metres.

speed = distance/time

speed (km/h) = 1440/2.5

                      = 576 km/h

speed (m/s) = 14,40,000/9000

                    = 160 m/sec.
