sagar and akash ran 2km ran twice. Akasah completed the first round 2 minutes earlier than sagar.In the second round sagar increased his speed by2km/hr.sagar finished 2 minutes earlier than akash. find their speeds of runnins in the first round.
Solution:
Sagar: x
Akash: y
So
2/x - 2/y = 2/60
2/y - 2/(x+2) = 2/60
So
x = 6.81
y = 7.68
So the speed of Sagar is 6.81 km/h, the speed of akash is 7.68 km/h
