    one type of lightning bug glows once every 1 1/2 seconds. how many times can it glow in 1 minute

    Divide 60 by 1.5

    Bea can run 1/6 mile in 2 minutes. how long should it take her to run 2 miles?

    Cross multiply and solve this proportion for x.

    (1/6)/2 = 2/x

    So the first one is 40

  • social studies -

    Second one is 3? I don't know

  • social studies -

    Or is it 6?

  • social studies -

    (1/6)/2 = 2/x

    (1/6)x = 4

    x = 4/(1/6)

    x = 4 * (6/1

    x = 24 minutes to run 2 miles

    Thank you but you know what the problem is I showed to my teacher like I don't know how many times 24 and she said its wrong but I don't care I'm going to sure her and that's that. Was I right for the light bug 40?

    Yes, 40 is correct for the first one about the lightning bug.

    Another way to solve the miles/minutes problem is this way.

    She runs 1/6 of a mile in 2 minutes. It must take her 12 minutes to run 1 mile. So she take 24 minutes to run 2 miles.

    Thank you but guess what ? I showed her about the lightning bug and she said it was still wrong. I don't get it I got the other one right though do you think there's another way if not that's okay but thanks anyways.
