Question

you ride your bike to a store, 4 miles away, to pick up things for dinner. when there is no wind, you ride at 10 mi/h. today your trip to the store and back took 1 hour. write a rational equation you can use to find the speed of the wind today. solve the equation.

Answer 1

4 miles= (10-s) x 1hr. S could stand for the speed of the wind, since it is taking away from the typical speed of the bike.
