60 ft /sec equals _____ km/ hours

BabaBlast [244]

60ft/s

60ft = 0.3048 × 60 m = 18.288 m

Thus 60ft/s = 18.288 m/s

$1 \: \frac{m}{s} = \frac{1}{1000} km \div \frac{1}{3600} h \\ \\ = (\frac{1}{1000} \div \frac{1}{3600} ) \: \frac{km}{h} \\ \\ = ( \frac{1}{1000} \times 3600)\: \frac{km}{h} \\ \\ = \frac{18}{5} \: \frac{km}{h}$

$18.288\: \frac{m}{s} = (18.288 \times \frac{18}{5})\: \frac{km}{h} = 65.84\: \frac{km}{h}$

Hence, 60 ft/s = 65.84 km/h
