a monkey climbs 30m at the beginning of each hour and fall back 20m during each hourly period . if he begins his ascend at 8:00am at what time will he first make contact with the point 70m distant from the ground?

  1. At 9 he was at 10 m
    10 -- 20 m
    11 -- 30 m
    12 -- 40 m
    1 -- 70 m

    When he reached 70 m, he didn't have a chance to fall back again.
