Answer:
Step-by-step explanation:
3/8 miles long, 1/48 miles per hour
3/8 and 1/48 can have a common denominator, so you make 3/8 into 18/48 by multiplying both the numerator and denmoinator by 6.
18/48 miles long
1/48 per hour
divide: 18/48 divided by 1/48, which turns into 18/48 x 48/1 which equals 18
18 hours
You can set them equal to each other so -3x+4=4x-10 and then you add 3x and 10 on both sides and get7x=14 and then divided both sides by 7 and get x = 2 and check by plugging in and you get -2 for y on both so solution is x=2
