  2. 2nd snail goes 35 cm in 7 minutes
    so 35/7 in 1 minute, so
    In 1 minute it goes 5 cm
    then in 1 hr, 10 or 70 minutes it would got
    70(5) or 350 cm

    4th snail:
    39 cm in 6 minutes
    100 cm in (6/39)(100) = 600/39 minutes
    or 1 m in 600/39 minutes
    1000 m in 600000/39 minutes
    1 km in 15384.6 min = 256 hours, 25 minutes.

    Why is all the other data given?
