Question

The equation Y equals 4/10 X describes the number of kilometers y that a van travels in x minutes. What is the constant speed of the van in terms of hours?

Answer 1

`(4)/(10)=0.4` kilometers per hour.

Explanation:

We have been given an
`y=(4)/(10)x`, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.

We can see that van travel
`(4)/(10)x` kilometers in x hours. To find the constant speed of van, we will substitute
`x=1` in our given equation as:

`y=(4)/(10)(1)`

`y=(4)/(10)`

Since van travels
`(4)/(10)` kilometers in one hour, therefore, constant speed of van is
`(4)/(10)` kilometer per hour or
`0.4` kilometers per hour.
