Question

express the following in m/min:a.1 km/h (b)60km/hr.

Answer 1

Answer :

We know that,

   1 km = 1000 m and 1 h = 60 min

a) We need to find : 1 km / h = ? m / min

So, 1 km / h = ( 1 km ) / ( 1 h )

= ( 1000 m ) / ( 60 min )

= 1000/60 m / min

= 5/3 m / min

b) We need to find : 60 km / h = ? m / min

So, 60 km / h = ( 60 km ) / ( 1 h )

= ( 60 * 1000 m ) / ( 60 min )

= ( 60 * 1000 / 60 ) m / min

= 1000 m / min
