Step-by-step explanation:

Given two points A and B are 150 km apart. kunal leaves point A towards point B by bike at uniform speed of 50 km per hour after 1 hour hemant leaves point B towards point A by car at a uniform speed of 60 km per hour each of them stops at a point 15 km from the starting point for 12 minutes. find the distance between point A and the point where they meet

Now two points are point A and point B.
So Kunal speed is 50 km/hr. Also he stops at a point 15 km from the starting point.
So time taken will be 15 / 50 x 60 = 18 minutes.
So he stops for 12 minutes. So total time will be 18 + 12 = 30 minutes.
So Kunal covers a distance of 30 / 60 x 50
= 25 + 15
= 40 km
Before Hemant leaves point B Kunal covers a distance of 40 km
Now time taken by Hemant to reach the stopping point will be 15/60 x 60 = 15 min
Also he stays for 12 min and so total time will be 15 + 12 = 27 min
So distance covered by Kunal in 27 min will be 27 / 60 x 50 = 22.5 km
So total distance will be 40 + 22.5 + 15 = 77.5 km
Therefore remaining distance will be 150 – 77.5
= 72.5 km
Now time taken to meet each other will be 72.5 /110 (50 + 60 = 110)
0.659
So distance between point A and the point where they meet will be
= 0.659 x 50
= 32.95
So distance will be 32.95 + 62.5
= 95.45 km
