Question

32.5 metres per sec in to km/ hours

Answer 1

1m = (1/1000)km
1s. = (1/60) min = (1/(60*60)hrs = (1/3600) hrs

Substituting the values
32.5 m/s
=32.5 x (1/1000)/(1/3600) km/hr
=32.5 x(3600/1000) km/hr
= 32.5 x (18/5) km/hr
= 117 km/hr

Answer 2

32.5 x 18/5
= 32.5/5 x 18
= 6.5 x 18 = 117

Answer is 117km/h
