Question

a car takes 4hrs to cover a distance ,if it travels at speed of 40mph. what should be its speed to cover the same distance in 1.5 hr???​

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
