help please?? Lou was 20 miles from home at 1pm and 120 miles from home at 3pm. What was Lou’s average rate of travel during that time? *

Answer 1

We know that distance traveled is equal to rate multiplied by time - or in a formula d=rt, where d is distance, r is average rate, and t is time. Distance can be measured in many units, including miles, feet, meters, etc, while time can be measured in minutes, hours, seconds, etc.

Here, we're told that Lou was 20 miles from home at 1pm and 120 miles from home at 3pm. Between 1pm and 2pm, Lou must have traveled 100 miles. He covered that time in 2 hours. Using the formula, we have that r=d/t, or in this case:

rate = 100 mi / 2 hr = 50 miles/hour.
