Ladder math
A boat stationed at the coast has a rope ladder tied to the deck such that the
13th
cross step (from the deck) touches the sea level.
Each cross step has a distance of
1ft
(between each cross step).
The tides causes the sea level to rise at the rate of
0.5 m/hr
.And the tide takes
4 hr
to completely rise and fall.
How many times does the sea level cross(or touch) the
10th
cross step (from the deck) in
a day
?
