We know that
Speed = distance/time
65 = distance/48mins
Distance = (speed)(time)
Distance = 48 x 65 = 3120
Now, to find the required speed if the time taken = 40 mins
Speed = distance/time
Speed = 3120km/40 mins
Speed = 78 kilometres per hour
Speed = distance/time
65 = distance/48mins
Distance = (speed)(time)
Distance = 48 x 65 = 3120
Now, to find the required speed if the time taken = 40 mins
Speed = distance/time
Speed = 3120km/40 mins
Speed = 78 kilometres per hour
