I'm not quite sure how to set this problem up. This is the first of the entire worksheet and I'm sure if I understand one problem I can finish the rest pretty easily.

Question

The problem states: When there is no wind, Amelia flies her plane from Oklahoma City to San Francisco in exactly 4 hours, at an average speed of 325 mph. If she were flying into a 25-mile-per-hour head wind, how long would the trip take?

Answer 1

distance = rate*time
d= 325 x 4 = 1,300 miles.

If flying into a 25 mph head wind, then the speed is just 325-25 = 300. Plug in d and r and calculate time.
