Solve for the indicated variable:

The safe load L of a wooden beam supported at both ends varies jointly as the width w and the square of the depth d and inversely as the length l. A 3 in. wide by 10 in. deep beam that is 8 ft long supports a load of 9600 lbs safely. What is the safe load of a beam of the same material that is 4 in. wide, 9 in. deep, and 12 ft long?

A carpenter and his partner can put up a patio cover in 3 and 3/7 hours. If the partner needs 8 hours to complete the patio alone, how long would it take the carpenter working alone?

It takes Rosa, traveling at 30 mph, 30 minutes longer to go a certain distance than it takes Melody traveling at 50 mph. Find the distance traveled.
