Johan travels at a rate of 2 miles per hour.

Johan travels at a rate of 20 miles per hour.

Answer 1

To find Johan’s rate of speed in miles per hour, we can use the given information and plug it into the distance formula.

The distance traveled (d) is 35 miles, and the length of time traveled (t) is 1.75 hours.

Using the formula d = rt, we can now solve for r:

35 = r * 1.75

To isolate r, we divide both sides of the equation by 1.75:

r = 35 / 1.75 = 20

Therefore, Johan’s rate of speed is 20 miles per hour.
