Question

54 $\frac{km}{h}$ = ___ $\frac{m}{s}$

• A. 15 m/s
• B. 1.5 m/s
• C. 5.4 m/s
• D. 5 m/s

Answer 1

The correct option is A

15 m/s

We know,1 $\frac{km}{h}$ = $\frac{5}{18}$ $\frac{m}{s}$

Now 54 $\frac{km}{h}$ = 54 $\times$ 1 $\frac{km}{h}$

= 54 $\times$ $\frac{5}{18}$ $\frac{m}{s}$

= 3 $\times$ 5 $\frac{m}{s}$

= 15 $\frac{m}{s}$
