Come on, I was doing this kind of thing at the age of 9. If you're old enough to be p osting on Yahoo (minimum age of 13) you should be able to do this in your head.

Recall that v = s/t -- (1) Making t the subject of formula in (1), we have t = s/v -- (2) From the question, s = 8 mi and v = 178 mi/hr. By substitution, we have (2) to be expressed as t = 8/178 Therefore, t = 0.0449 hr.

A Helicopter is traveling 178 miles per hour. It would take 2.7 minutes to get to its destination 8 miles away.
