A person crosses a 500 m long street in 10 minutes. What will the person's speed be in kilometres per hour? Correct Answer 3 km/h

Given

Distance = 500 m

Time = 10 minutes

Formula used

Speed = Distance/time

1 Hour = 60 minutes

1 km= 1000 m

Calculation

Distance = (500/1000)km

⇒ 1/2 km

Time = (10/60)hours

Speed = (1/2)/(10/60)

⇒ (1/2) × (60/10)

⇒ 3 km/h

∴ The person's speed be in kilometres per hour is 3 km/h
