Question

How many hours will it take to cover a distance of (x+120)km with the speed 40km/h​

Answer 1

Answer:

It’s a simple ratio. The product of the means equals the product of the extremes. In other words:

120 is to 3 as 150 is to x (unknown)

120 / 3 = 150 / x

So divide the product of the means (3 * 150 = 450) by the product of the extremes (120x)

450/120x = 3.75

So the answer is 3 3/4 hours = 3 hours and 45 minutes

Answer 2

Answer:

33/4=3hour or 45 minutes
