Think carefully about this problem.
.
60 miles is 3 times the distance (20 miles) that you travel in 1/5 of a second .
.
Therefore, it will take you 3 times the time that it takes you to go 20 miles.
.
Since it takes you 1/5 second to go 20 miles, it will take you 3 times that or 3/5 second to go 60 miles. That's the answer ... 3/5 of a second.
.
That's fast! Since you go 20 miles in 1/5 second in 5/5 (or 1) second you will go 5 times 20 miles or 100 miles each second. And since there are 60 seconds in a minute, you will go 60 times 100 miles in a minute. That's 6,000 miles per minute. And since there are 60 minutes in an hour, you will go 6,000 times 60 or 360,000 miles in an hour.
