We can determine the time it would take an object to fall (if there were no air resistance) by using the formula where d is the distance.
A. How long does it take a quarter dropped from a 35 foot roof to reach the ground?
B. If there are 5,280 feet in one mile, how long would it take an object to fall miles?
C. If it takes an object 5.9 seconds to fall d feet, how tall is the object?

You left out the formula (which you should know) and did not say the number of miles in question B.
Please show your work if you would like further assistance. 
Jimmy is going to rent a car to on vacation. the rental will cost 150 plus .75 for every mile he drives. write an equation for this problem if jimmy plans 500 miles how much will the rental cost him?
