Hi Jaden:

Units, units,units ...

(miles/hour)(hours) = miles

(60 mph)(2 hours) = 120 miles

(inches/foot)(feet) = inches

(12 in/ft)(3.5 ft) = 42 inches

(cars/block)(BLOCKS) = cars

(25 cars/block)(10 blocks) = 250 cars

.

Looking at the units and pretending they are individual FRACTIONS will tell you

most times how to manipulate the information given to obtain what you need.

(feet)(miles/feet) = miles

(21120)(1/5280) = 4 miles
