You would like to know how many miles
you travel in +60+ min, since that
would be miles / hour
----------------------
Rate = +12%2F50+ mi/min
Divide top and bottom of the rate by +50+
+%28%28+12%2F50+%29%29+%2F+%28%28+50%2F50+%29%29+=+%28%28+12%2F50+%29%29%2F1+ miles / min
+%28%28+6%2F25+%29%29+%2F+1+ miles / min
---------------------------
Convert +2+ hrs to minutes:
[ hrs ] x [ min / hr ]
+2%2A%28+60%2F1+%29+=+120+ min
--------------------------
Now use +d+=+r%2At+
+d+=+%28%28+6%2F25+%29+%2F+1+%29%2A120+
+d+=+720%2F25+
+d+=+28.8+
You travel 28.8 mi in 2 hrs
--------------------------
check:
+d+=+r%2At+
[ mi ] = [ mi/min ]
+28.8+=+%28+12%2F50+%29%2A120+
+28.8+=+28.8+
