A man covers a certain distance in 2 hours 45 min, when he walks at the rate of 8 km/h. How much time will he take to cover the same distance if he runs at a speed of 33 km/h?
Explanation:
2 hours 45 mins = 2 + 45/60 = 11/4 hours.
∴ Distance = Speed × time = 8 × 114= 22 kms.
⇒ Time taken while running at 33 kmph = 2233 hrs = 2233 × 60 mins = 40 mins
Hence, option (a).
