Question

The AVG. Speed of a snail is 0.020miles/hr. And that of leopard is 70miles/hr. Convert this speeds in SI units

Answer 1

Given ⇒

Average Speed of the Snail = 0.020 miles/hours.

∵ The S.I. Unit of Speed = m/s.

So, converting the Quantity into m/s.


∵ 1 miles = 1609.34 m.

∴ 0.020 miles = 0.020 × 1609.34
= 32.1868 m.

Time = 1 hrs

= 60 × 60 seconds.

= 3600 seconds.

∴ Average Speed of the Snail in km/hr.
= 32.1868/3600 m/s.
= 0.00894 m/s.



Speed of the Leopard = 70 miles/hours.

70 miles =
70 × 1609.34 km.
= 112653.8 m.

1 hrs= 3600 seconds.

∴ Speed of the Leopard in km/hr.
= 112653.8/3600 m/s.
= 31.29 m/s.
