Answer:

15km / hour - 14km/hour..

Verified answer

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
