Verified answer
Speed distance travelled / time of motion
Therefore,
distance travelled = speed x time of motion
PRICING
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 O
+ 30 Km = 45 Km
