Math Papa is a very good calculator. You can try it. Just put the equation www.mathpapa.com :)
I solved it on a piece of paper. I can not answer why I got the same answer, but I hope my method helped
Answer:
21.75 miles
Step-by-step explanation:
2 hours=14.5 miles
3 hours=x
2x=14.5*3
x=
A) x - 7 > 3 |add 7 to both sides
x > 10
b) x - 7 > 3 |add 7 to both sides
x > 10
It would be twice whatever the midsegment equals.
