Question

60 ft /sec equals _____ km/ hours

Answer 1

60ft/s

60ft = 0.3048 × 60 m = 18.288 m

Thus 60ft/s = 18.288 m/s


`1 \: (m)/(s) = (1)/(1000) km / (1)/(3600) h \\ \\ = ((1)/(1000) / (1)/(3600) ) \: (km)/(h) \\ \\ = ( (1)/(1000) * 3600)\: (km)/(h) \\ \\ = (18)/(5) \: (km)/(h)`


`18.288\: (m)/(s) = (18.288 * (18)/(5))\: (km)/(h) = 65.84\: (km)/(h)`

Hence, 60 ft/s = 65.84 km/h
