oliver can jog about 3 times as fast as he can walk. If his average walking rate is one mile in 20 minutes, about how far could he jog in 2 hours?

  • math -

    walking rate = 1/20
    jogging rate = 3times or 3miles/20 minutes

    2 hours = 120 minutes
    Can you finish from here?

  • math -

    I'm not getting it yet?

  • math -

    you can cover 3 miles every 20 minutes
    You are walking for 12o minutes.

    3 miles/20 minutes = x miles/120 minutes.

    The denominator of 120 is 6 times bigger than the denominator of 20.

    so you should go 6 times farther.

  • math -

    so she could go 40 miles in 2 hours because 120/3=40

    No wait is it 18 miles?

  • math -

    18 miles is right.
