Question

Two hot air balloons are flying above a park. One balloon started at a height of 3,000 feet above the ground and is decreasing in height at a rate
of 40 feet per minute. The second balloon is rising at a rate of 50 feet per minute after beginning from a height of 1,200 feet above the ground.

Given that h is the height of the balloons after m minutes, determine which system of equations represents this situation.
A. h=3,000-40m
h=1,200+50m

B. h=3,000+40m
h=1,200-50m

C. h=3,000m-40
h=1,200m+50

D. m=3,000-40h
m=1,200+50h

Answer 1

Answer:

A

Step-by-step explanation:

the first balloon starts at 3,000 and goes down 40 so this would make it a negative 40 so 3,000-40 but it does this every minute so 3,000-40m

the second balloon is going up starting at 1,200 and going up by 50 so positive 50 this would be 1,200+50 and it does this every minute so 1,200+50m
