No, they are not. You can write ratio in different ways, so I did 2/3 = 9/6. I cross product, which is 2 × 6 and 9 × 3. Both of the answer did not match, so that tells me they are not proportional.
1) C 392 in2
2) 125cm³
3) D 64 in3
Remark
The question becomes "How long does it take her to drive 248 + 93 = 341 miles?"
Answer
Set up a simple proportion.
248/4 = 341/x Cross multiply
248 * x = 4 * 341
248 x = 1364 Divide by 248
x = 1364/248
x = 5.5 hours
But you are only asked about the 93 miles.
Answer: The number of hours for 93 miles is 5.5 - 4 = 1.5
We can divide 4424 by 56 to find our length. 4424/56 is 79. Therefore, the length is 79m. To check our answer, we can multiply 79*56. 79*56 is 4,424.
