Question : 24

Total: 40

18\,\text{km}/\text{h}

Solution:

Concept:

Time is found by dividing distance by speed:

\text{Time} = \frac{\text{Distance}}{\text{Speed}}

Explanation:

Distance covered

= 150\,\text{km}

Speed

= 18\,\text{km/h}

So,

\text{Time} = \frac{150}{18}

Simplify:

\frac{150}{18} = \frac{25}{3}

hours.

Convert

\frac{25}{3}

hours into hours and minutes.

\frac{25}{3} = 8\frac{1}{3}

hours.

Now convert the fraction part to minutes.

\frac{1}{3}

hour

= \frac{1}{3} \times 60 = 20

minutes.

Therefore, total time taken is

8

hours

20

minutes.

Answer:

8 hours 20 minutes, which is Option D.
