Joe drives 20 miles in ½ hour. How long will it take him to drive 50 miles?

To find out how long it will take Joe to drive 50 miles, we can use the method of finding the unit rate and then multiplying it by the desired distance.

Joe drives 20 miles in ½ hour, so his rate is 20 miles / 0.5 hour = 40 miles per hour.

To find out how long it will take him to drive 50 miles, we can use the formula: time = distance / rate.

time = 50 miles / 40 miles per hour = 1.25 hours.

So, it will take Joe 1.25 hours to drive 50 miles.
