To mountains took 9 Hrs at x mph where x = No of miles to mountains
No of miles travelled = 9x
From mountains took 4 hours at (x+40) mph
No of miles travelled = 4(x+40)
Therefore 9x=4(x+40) thus 9x=4x+160 thus x=32 = distance Charmaine lives from the mountains
P = 2(L + W) ....this is the perimeter of a rectangle
P = 40
L = 5
40 = 2(5 + W)
40 = 10 + 2W
40 - 10 = 2W
30 = 2W
30/2 = W
15 = W <=== ur answer is 15 ft
Answer:
There are equal ratios
Step-by-step explanation:
100/25=4 and 15x4 is 60
100/20=5 and 12x5 is also 60
