Question

At a speed of 15 kilometres per hour, it takes me 8 hours to reach at a point. If the time taken by me to reach at same point is 5 hours, then my speed would be

Answer 1

Explanation:

Hi, there!!!

According to the question,

1st case

At the speed of 15 km/ hr, it takes time 8 hrs to reach a point.

Then, we must find the distance first to calculate your speed in 2nd case,

So, let's find the distance first,

now,

distance (d) = s×t

or, d= 15km/ hr × 8hrs

Therefore, the distance is 120 km.

now,

In 2nd case,

As the question has asked to find speed on same point, it will have same distance covered.

time( t) = 5hrs.

distance (d)= 120km

now,

speed = distance/time taken

or, s= 120 km/5 hrs

or, s = 24km/ hr.

Therefore, your speed in 2nd case will be 24km/hr.

Hope it helps...

Answer 2

24 kilometers per hour

Explanation:

15 kph x 8 h = 120 kilometers

120km/5 hours = 24 kph
