Answer 1

Answer:

The distance between two town is 300km.two car simultaneously from these town and move towards each other .The speed of one car is more than other by 7km/hr if the distance between the car after 2hours is 34 km ,find the speed of car

Answer

Let the speed of car B be x km/h.

Then, speed of car A =(x+7) km/h

Now, distance covered by car B in 2 hours=2x km and

Distance covered by car A in 2 hours =2(x+7) km

Given, distance between the cars after two hours is 34 km and distance between both the towns is 300 km.

So, distance covered by both the cars in two hours moving in opposite direction =300−34=266 km

⇒2(x+7)+2x=266

⇒2x+14+2x=266

⇒4x=252

⇒x=63 km/h

Therefore, speed of car B =63 km/h and speed of car A =63+7=70 km/h.
