Question

a car takes 4 hours to cover a distance, if it travels at speed of 40 mph.What should be it,s speed to cover the same distance in 1.5 hours?

Answer 1

Answer:

Here, time t =4 hour

Speed V = 40 miles/ hr

So distance d = V×t = 4×40 = 160 miles.

Now the speed will be its cover this distance in 1.5 hours.

V= d/t = 160/ 1.5 = 106.67miles/hr

So the speed is 106.67miles/hr

Answer 2

Given:

Speed of car=40mph

Time taken=4 hours

To find:

The speed of the car to cover the same distance in 1.5 hours

Solution:

The speed of the car to cover the same distance in 1.5 hours is 106.67 mph.

We can find the speed by following the given steps-

We know that the distance covered by the car is the product of its speed and time.

Let the distance covered by the car be D.

Now, the time taken by car to cover D is 4 hours at a speed of 40 mph.

Distance covered= Speed of car× time taken by the car

D=40×4

D=160 miles

Now, to cover the same distance in 1.5 hours, let the car travels at a speed S.

The distance covered=160 miles

Time taken=1.5 hours

Distance covered= Speed of car× time taken by the car

160=S×1.5

S=160/1.5

S=1,600/15

S=106.67 mph

Therefore, the speed of the car to cover the same distance in 1.5 hours is 106.67 mph.
