How long would it take the 4th snail to travel 1km?
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?
