    Fast Question

    Hey, just in need for some quick help: Peta is on her way to her friend Joey's house. She walked a certain distance, w (km) and then ran five times as far as she walked. She was finally picked up by Joey's Mum and driven the remaining 10 km to his house!
    a) Write an expression, in terms of w, for the total distance that peta travelled. Simplify your answer.

    The total distance to joey's house is 22km i think,

    b) write an equation relating w to the total distance travelled.
    c) solve your equation to determine how far peta walked.
    d) How far dod Peta Run

    Okay is there a way, or "Steps" that will enable me to always be able to solve questions like this? Thanks

    a) Write an expression, in terms of w, for the total distance that peta travelled. Simplify your answer.
    she walked w km
    then she ran 5 times as far as she walked, which is 5w km
    then she got picked up, and was driven 10 km

    the sum of these is the total distance travelled

    thus, total distance = w + 5w + 10 = 6w + 10

    The total distance to joey's house is 22km i think,

    b) write an equation relating w to the total distance travelled.
    6w + 10 = 22

    c) solve your equation to determine how far peta walked.
    i think you can handle this

    d) How far dod Peta Run
    multiply the answer to the last question by 5
