A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. The total distance covered by the car is:
(i) 100 km
(ii) 25 km
(iii) 15 km
(iv) 10 km
Firstly, the car is moving with a speed of 40kmhr for 15 minutes.
Distance covered =speed×time= 40×14=10 km
Secondly, the car is moving with a speed of 60kmhr for 15 minutes.
Distance covered = 60×14=15 km
Total distance covered = 10 km + 15 km = 25 km
