GRAD - B.S. w/Honors SEE TUTORS LIKE THIS 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 |
