Answer:
105 mph = rate of first plane
130 mph = rate of second plane
Step-by-step explanation:
Let r = rate of first plane
then r + 25 = rate of second plane
2r = distance of first plane
2(r + 25) = distance of second plane
2r + 2(r + 25) = 470
2r + 2r + 50 = 470
4r = 420
r = 105 mph
r + 25 = 130 mph
Answer:
The new width is 3 in.
Step-by-step explanation:
We can use the ratio of w/h, the origal width and height should have the same ratio as the new width and height.
<u>12 </u>= <u>x</u>
16 4
Then solve for x:
x = 4 (12/16)
x = 3
To check:
12/16 = 3/4
3/4 = 3/4
