The average change of altitude per minute would simply be
the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
<span>average change of altitude = 0.55 mile / minute</span>
Step-by-step explanation:
Below is an attachment containing the solution.
It's 6/35 because of means multiply and take numerator times numerator and denominator times denominator when you multiply fractions. 2 x 3 = 6 over 5 x 7 = 35. 6/35.
-2x+y=5
Multiply everything by-1
2x-y=-5
