Question

A car travels for 6 hours and covers a distance at the
speed of 60 km/h. If it travels at the speed of 90 km/h,
then how much less time will it take to cover the same
distance?​

Answer 1

Step-by-step explanation:

At first we find what is the distance:

the formula for distance =speed×time

(let distance =x)

x=60×6

x=360

Now, we find time for solve this question

distance=speed×time

360=90×x

360÷90=x

4=x

when a car travel with 90km/h the time taken is 4 hour.

and when car travel with 6km/h time taken is 6hours.

So, 2 hours are less.
