A runner covers 200 meters in 22 seconds. Find his approximate speed in km/h.
Correct Answer: Option B
Explanation:
Speed = 200 / 22 m/s = 100 / 11 m/s. In km/h = (100 / 11) * (18/5) = 360 / 11 = 32.72 km/h.
Speed = 200 / 22 m/s = 100 / 11 m/s. In km/h = (100 / 11) * (18/5) = 360 / 11 = 32.72 km/h.

A car traveling at 60 km/h covers a certain distance in 4 hours. At what speed must it travel to cover the same distance in 3 hours?
Correct Answer: Option C
Explanation:
Distance = Speed * Time = 60 * 4 = 240 km. Required Speed = Distance / New Time = 240 / 3 = 80 km/h.
Distance = Speed * Time = 60 * 4 = 240 km. Required Speed = Distance / New Time = 240 / 3 = 80 km/h.
