Answer:
Explanation:
Given That
To cover a distance of 240km, a car has to increase the speed by 5km/hr to reach in time. If the time lost was 40 minutes during traffic jam, find the original speed of the car.
.
increased speed of car = 5km/hr .....(speed 1st)
distance travelled = 240km
speed = distance travelled / time taken
= 240 / 40
= 6
thus,
speed = 6km/hr .....(speed 2nd)
.
therefore original speed
= speed 2nd - speed 1st
= 6-5
= 1
Ans. thus, the original speed of the car is 1km/hr.
