Answer:
8 hours
Explanation:
In the problem, it gives you the formula: d=rt, and in the rest of the problem it gives you the distance and the rate, so all you have to do is plug the numbers in and solve.
360m = 45mph(t)
Isolate the variable by dividing 360 by 45
360/45 = t
8 = t
This means that it will take 8 hours to travel 360 miles at a rate of 45 miles per hour.
Hope this helps :)
