Answer:
606.6 and 233.3 respectively
Step-by-step explanation:
Let the speed of plane in still air be x and the speed of wind be y.
ATQ, (x+y)*9=7560 and (x-y)*9=3360. Solving it, we get x=606.6 and y=233.3
Answer: 1 1/3 packs of treats
2 1/9 + 5/9 = 2 6/9, which can be simplified to 2 2/3.
We subtract 2 2/3 from 4, giving us 1 1/3
B 100
32+48 = 80
Four equivalent expressions are:
40+40 = 80
20+60 = 80
10+70 = 80
30+50 = 80
