Answer:

Find the time taken to cover the distance from Delhi to Agra, a distance of 360 km, by the Shatabdi express moving at 20 m/s. d) 6 hours. Explanation: Moving at 20 m/s = 20 × (18/5) km/h= 72km/h. Time = 360 /72 = 5 hours.

Answer 2

Explanation:Distance=360 km

Speed= 20 m/s

          =20*1000/3600                                         [1km = 1000m & 1hr= 3600s]

          =20*5/18

          =50/9 km/hr

speed= distance/time

therefore, time= distance/speed

                         =360/50/9

                         =360*9/50

                         =64.8 hrs
