Question

A cyclist covers 450 metre in 2 minutes. Find his speed in km/ hr.

• A. 13.5 km/hr
• B. 11.5 km/hr
• C. 12.4 km/hr
• D. 15 km/hr

Answer 1

The correct option is A 13.5 km/hr

Distance traveled = 450 m = $\frac{450}{1000}$ = 0.450 km
Time taken = 2 minutes = $\frac{2}{60}=\frac{1}{30}$ hours
Speed = $\frac{distance}{time}=\frac{0.450}{\frac{1}{30}}=0.450\times 30$
= 13.5 km/hr
