Answer:
Step-by-step explanation:
-1+8=7
20,000,000+400,000+80,000+4,000+100+60+3
The descent of the balloon would take 14 minutes
To find the answer to this problem, take the elevation change (315) and then divide it by the rate of descent (22.5)
Divide -38 by -5
The negatives cancel out since a negative divided by a negative is a positive.
7.6
Using a calculator I put 1,284/26=49.384615385. Rounded to tenth: 49.4 :)
