Question

A garden snail traveled 1⁄40 of a mile in 1⁄2 an hour. What was the speed of the snail?

Answer 1

A mile=5280 feet
1/40 mile*(5280 feet/1 mile)=132 feet

132 feet-------------------1/2  hour
x------------------------------1 hour
x=(132 feet*1 hour) / (1/2 hour)=264 feet/hour.

264 feet/h *(1 mile/5280 feet)=0.05 miles/ h

Solution:  S=264 feet/h  (≈0.05 miles/h)
