Question

 A car travelled a distance from town A to town B, which is 77 km in 3 hours 30 minutes. Find the speed of the car in metre per second​

Answer 1

speed = distance by time

speed = 77000/330

Answer 2

Given Data :

Distance = 77km

⇒ 77 x 1000m = 77,000 m

Time = 3hrs 30mins = 180 + 30 mins

⇒ 210 x 60 sec = 12,600 sec

To Find :

Speed of car (in m/s)

Solution :

Speed = distance/time

⇒ 77000/12600

⇒ 6 m/s [approx.]
