Question

Q. The average speed of a mail is 0.020 miles/hour and
that of a leopard is 70 miles /hour. Convert these speed
in ST units​

Answer 1

Hello Dear.

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.

Hence, the Speed of the Leopard in m/s is 31.29 m/s.

Hope it helps.
