Mitch has 3 tests to study for on Thursday night. He needs to spend twice as much time on Science as English. He also has to study Math and he can learn that in 1/2 the time it takes to study English. He has four hours to study. What is the maximum amount of time, to the nearest tenth, of an hour, that he can study English?

    let time for math be x hrs
    then time for English is 2x hrs
    time for science is 4x

    4x+2x+x = 4
    7x = 4
    x = 4/7 hrs

    math -- .57 hrs
    English -- 1.14 hrs
    Science -- 2.29 hrs
