Question

the distance between the house and school of a boy is 3.6 km .if he takes 6 min .to reach his school by car calculate his speed in m/s also express his speed in k/h

Answer 1

Distance=3.6km Or 3.6×1000=3600m

Time = 6minutes Or 6×60=360seconds

Speed =Distance÷ Time

=3600÷360=10m/s

In km/h,

speed=3.6÷.1=36km/h

Answer 2

Answer:-

Explanation:

Given:-

Distance (d) = 3.6 km = 3.6 × 10³ m

Time (t) = 6 min = 6 × 60 = 360 sec = 6/60 h

To Calculate:-

Speed (u) = ???

In m/s and km/h

Formula to be used:-

v = d/t

Solution:-

In km/h

⇒ v = d/t

⇒ v = 3.6/6/60

⇒ v = 3.6 × 60/6

⇒ v = 36 km/h

In m/s

⇒ v = d/t

⇒ v = 3.6 × 10³/360

⇒ v = 10 m/s
