A car travels with speed 30km /h for 30mins .and then with speed 40km/h for one hour find the total distance traveled by the car
Asked by qudsia988020 | 3rd Oct, 2018, 09:00: PM
Expert Answer:
Speed = distance travelled / time of motion
Therefore,
distance travelled = speed x time of motion
In 30 minutes i.e 0.5 Hr, the car travelling with the speed of 30 Km/Hr will cover
= 30 x 0.5 = 15 Km distance
If the same car travells with the speed of 40 Km/Hr for 1 hour, the car will cover
= 40 x 1 = 40 Km
Therefore, the total distance travelled by the given car is 15 Km + 30 Km = 45 Km
