How much time a person take to cover a distance of 300 metre, if he runs at a speed of 10 km/h?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1 min 48 sec
Formula used
Speed = Distance covered/Time taken
Given that
The distance covered = 300 m
Speed = 10 km/h = 50/18 m/s
Calculation
⇒ (50/18) = 300/Time
⇒ TIme = 300 × 18/50
⇒ Time = 6 × 18 = 108 sec = 1min 48 sec
