During his morning walk. Atul walks for 45 minutes at a speed of 8 km/h and takes 15 rounds of a park. Shekhar takes 10 rounds of the same park in 40 minutes. What is the speed of Shekhar in km/h?

6

Distance covered by Atul in 15 round = 8 × \(\frac{45}{60}\) = 6 km

If 15 round = 6 km

1 round = \(\frac{6}{15}\) = 0.4 km

10 rounds = 10 × 0.4 = 4 km

Speed of Shekhar = \(\frac{40 × 60 }{40}\) = 6 km/h
