Question

Pihu and Aayu are running on a circular tack of diameter 28m, speed of pihu is 48 m/s and that of Aayu is 40 m/s. They start fom the same point at the same time in the same direction. When will they meet again for the first time?

Answer 1

Answer:

11

Step-by-step explanation:$\pi$$\pi$

2πr≈2×22/7×14≈88

relative speed=48-40=8

88/8=11

Answer 2

Answer:

11 seconds

Step-by-step explanation:

Diameter of circular track = 28 m

Radius = $\frac{28}{2}=14$

Length of the circular track = $2 \pi r = 2 \times  \frac{22}{7} \times 14=88$

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 = $\frac{88}{48-40}$

Time when they meet again for first time = $11$

Hence they will meet again in 11 seconds for the first time.
