d = r*t = 42*(4 55/60)

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.

Call the distance +d+
The rate is +42+ mi/hr
The time is +4+ hrs plus +55%2F60+ hrs
+55%2F60+=+11%2F12+
+4+=+48%2F12+
+48%2F12+%2B+11%2F12+=+59%2F12+
-------------
+d+=+r%2At+
+d+=+42%2A%2859%2F12%29+
+d+=+%28+21%2A59+%29+%2F+6+
It's about 210 mi
Calculate it and round off to nearest mile
