Pihu and Aayu are running on a circular track of diameter 28 m. Speed of Pihu is 48 m/s and that of Aayu is 40 m/s. They start from the same point at the same time in the same direction. When will they meet again for the first time?
Diameter of circular track = 28 m
Radius = $$\frac{28}{2}$$= 14
Length of the circular track = $$2\times pi\times r$$ = $$2\times pi\times 14$$ = 88m
Pihu and Aayu are running in the same direction at the same point .
We know that when two persons running in the same direction their speeds will be subtracted
Time = $$\frac{distance}{speed}$$
Time = 11
Time when they meet again for first time = 88/(48-40) = 88/8 = 11
Hence they will meet again in 11 seconds for the first time.
