After 3/4 of a minute a sloth has moved just 3/8 of a foot. What is the sloths speed in feet per minute??
we multiply both fractions by 4 so that we are working in whole numbers and get:
3 minutes(min) for 12/8 feet then we simplify 12/8 to 1.5 and have:
1.5 feet per 3 min divide both by 3 to get:
1/2 foot per minute or .5 ft/min
