Question

the speed of a car is 70khm-1 if it travels for 90 minutes at the same speed howb far or what distance will it covers? if it travels at 40khm-1 in the same time how far will it travel​

Answer 1

Answer:

1. Distance travelled = 105 km

2. Distance travelled = 60 km

Explanation:

speed = 70km / h

time = 90 min = 1.5 hour

Distance travelled = speed x time = 70 x 1.5 = 105 km

-------------------------

Now with different speed

speed = 40km / h

time = 90 min = 1.5 hour

Distance travelled = speed x time = 40 x 1.5 = 60 km
