A person crosses a 500 m long street in 5 minutes. What is his speed in km/h?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 6.
Formula used:
Speed = Distance/time ----- (1)
Calculations:
Time in seconds = 5 × 60 = 300 s
Speed = (500/300) = 5/3 m/s
Speed in km/h = (5/3) × (18/5)
= 6
