Answer:
1 apple= $0.4
Step-by-step explanation:
Let o=orange
Let a=apple
4o+5a=4
2o+3a=2.20
2o=2.20-3a
o=2.20-3a/2
Let's go balk to the the first equation
4o+5a=4
4(2.20-3a/2)+5a=4
4.4-6a+5a=4
4.4-a=4
-a=-0.4
a=0.4
Apple=$0.4

Step-by-step explanation:
The problem statement says λ<1. If this is true, then the cannonball is slower than the boat, and it will never reach the boat. So I assume it's actually λ>1.
If we say t is the amount of time, then the boat travels south a distance of ut, and the cannonball travels a distance of λut.
v = λut
ut = v/λ
Using Pythagorean theorem:
d² + (ut)² > v²
d² + (v/λ)² > v²
λ²d² + v² > λ²v²
λ²d² > (λ² − 1) v²
λ² / (λ² − 1) > (v/d)²
