Question

Convert each rate using dimensional analysis. round to the nearest tenth if necessary.

a.2640
b.264
c.880
d.2112

Answer 1

To convert 30 miles per hour to feet per minute, we use dimensional analysis in the process. 1 mile is equal to 5280 feet and 1 hour is equal to 60 minutes. Hence the formula of conversion is 30 miles / hour *(5280 ft/ mile) * (1 hour / 60 min). The answer is 2640 ft / min.
