SOLUTION: estimate the total distance you can travel in 4 hours 55 minutes if you drive on average 42 miles per hour. give your answer in whole miles

The other tutor doesn't understand that the idea here is to learn how
to ESTIMATE answers quickly in your head without a calculator, not to do 
them accurately as he did.  The idea is to get a ballpark answer.

4 hours 55 minutes is a little less than 5 hours and 42 miles per hour is
a little more than 40 miles per hours, so it's got be somwhere around 
40×5 or 200 miles.  You don't need a calculator to do that in your
head.

Estimate = 200 miles.
