Answer:
i. The distance between the balloon and canoe is 16.8 meters.
ii. The situation can be represented by: -12 + d = 4.8
Explanation:
Let the surface of the lake be zero. Then any position above it is taken to be positive, while any position below is taken as negative.
So that,
the balloon's vertical position = 12 meters
the sunken canoe's position = -4.8 meters
Given that the distance between the balloon and the canoes is d, then:
d = balloon's position - canoe's position
= 12 - (-4.8)
= 12 + 4.8
d = 16.8
The distance between the balloon and canoe is 16.8 meters.
Thus,
d = 12 -(-4.8)
d = 12 + 4.8
-12 + d = 4.8
The situation can be represented by: -12 + d = 4.8
