Question

A and B are two points 150 Km apart on a highway. Two cars start from A and B at the same time. If they move in the same directions, they meet in 15 hours. But if they move in the opposite directions, they meet in one hour. Find their speeds.​

Answer 1

Answer:

15km / hour - 14km/hour..

Answer 2

Step-by-step explanation:

Let the speed of Car which starts from A be x km per hour

And the speed of the Car which starts from B be y km per hour

Then according to the question

When cars move in the same direction till 15 Hour . then,

Distance covered by the car at A− distance covered by the car at B =150km

i.e.,15x−15y=150

Also according to the question when the car moves in opposite direction till 1 Hour. Then,

Distance covered by the car at A = distance covered by the car at B =150km

i.e.,1x+1y=150
