Question

Mr. Jain covered a distance of 864 km in 12 hours.Find the distance covered in one hour assuming that the speed remains the same throughout the journey.

Answer 1

Answer:

72 km.

The calculations is as follows:

Let the distance covered in 1 hr be x.

Total distance covered (d) :864 km

Total time taken (t) : 12 hours

So, speed (s) is given by:

$s = \frac{d}{t}$

Upon, putting the values in the formula, we get:

$s = \frac{864}{12}$

$s = 72 \:$

Hence, speed is 72 km/hr

Now, since speed is constant

$72 = \frac{x}{1}$

$x = 72$

Hence, the distance covered in 1 hr is 72 km.
