Question

A car travels 144/7 km in 12/7 h. Find the speed of the car in km/h.​

Answer 1

Answer:

Total distance covered = 744 km

Time taken = 12 h

As we know,

Speed = Distance/Time

So, 744/12 = 62

Avg. Speed of car is 62 km/h .

Answer 2

Given,

The distance covered in km$\[ = \frac{{144}}{7}\]$

The time taken to cover the given distance in hours$\[ = \frac{{12}}{7}\]$

Solution,

Formula used, $\[{\rm{Distance}} = {\rm{Speed}} \times {\rm{Time}}\]$

Therefore, the speed of the car is

$\[\begin{array}{l} = \frac{{\frac{{144}}{7}}}{{\frac{{12}}{7}}}\\ = \frac{{144}}{7} \times \frac{7}{{12}}\\ = 12\end{array}\]$

Hence, the speed of the car is$\[12\]$ km/hr.
