Question

A car covers a distance of 30 km and 250 metres in 25 minutes. The speed of the car in km per hour is ___________.

• A. 76.2
• B. 67.2
• C. 72.6
• D. 62.7

Answer 1

Answer:

C. 72.6

Distance = 30 km 250 m = (30.25) km

$Time = 25 minutes = (\frac{25}{60} = \frac{5}{12}) hours$

Speed:

$\text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{30.25}{5/12}$

$= 30.25 \times \frac{12}{5}$

$= \frac{30.25 \times 12}{5} = \frac{363}{5} = 72.6$

Final Answer:

$\boxed{72.6 \text{ km/h}}$
