Rich and John can mow a lawn in 40 minutes if they work together. If Rich works twice as fast as John, how long does it take John to mow the lawn alone? Tommy took a trip from Philadelphia to Pittsburgh, a distance of 300 miles. She traveled part of the way by bus, which arrived just in time for Wendy to complete her journey by train. The bus averaged 40 m/h and the rain 60 m/h. The entire trip took 5.5 hours. How long did Tommy spend on the train? Grain is falling from a chute onto the ground forming a conical pile whose diameter is always three times its height. How high is the pike when it contains 1200 ft3 of grain? Two television monitors sitting beside each other on a shelf in an appliance store have the same screen height. One has a conventional screen which is 5 in. higher than it is wide. The other has a wider, high-definition screen, which is 1.8 times as wide as it is high. The diagonal measure of the wider screen is 14 in. more than the diagonal measure of the smaller. What is the height of the screens? A storage bin for corn consists of a cylindrical section made of wire mesh, surmounted by a conical tin roof. The height of the roof is one-third the height of the entire structure. If the total volume of the structure is 1400π, and its radius is 10 ft., what is its height?
