Using distance = rate * time formula we can solve this problem.

We know the distance 40 miles and we know the time 2 hours.

Plug in the values.

40 miles = 2t hours

Solve for t.

Divide both sides by 2.

40 miles / 2 = 2t hours / 2
20 miles / hour = t

So, the answer is 20 miles per hour.

Answer:

The inverse is 5x+3

Step-by-step explanation:

y = (x-3) /5

Exchange x and y

x = (y-3)/5

Solve for y

Multiply each side by 5

5x =(y-3)/5 *5

5x = y-3

Add 3 to each side

5x+3 =y-3+3

5x+3 =y

The inverse is 5x+3
