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.
