Answer: In one hour Jack can Travel 5 miles.
Step-by-step explanation:
Jack can travel 20 miles in 4 hours. So to find out how many miles Jack can travel in 1 hour, we need to divide the number of miles for 4 hours (which is 20) by 4.
20 miles ÷ 4 hours = 5 miles in 1 hour
Therefore, we can say Jack can travel 5 miles in 1 hour.
