a car travels a distance of 715km at a uniform speed.if the speed of the car is 10 km/hr more , it takes 2 hrs less to cover the same distance.find the original speed of the car
Given : Total distance, D = 715 Km
To find : Speed of the car
Let the speed of the car be x km/hr.
When the car travels at uniform speed, time taken =
If it travels at a speed of 10 km/hr more, time taken =
and the difference of time taken is 2 hrs, so the equation becomes
As the speed cannot be negative, so speed of the train, x = 55 km/hr. (Answer)
