Can someone help me with this please

y=75

Step-by-step explanation:

Alright first off you want to be able to find the ratio to this to be able to find that Y you are looking for.

If you simplify y=45 and x=3 both by 3 you will get:

y=15 and x=1

now, lets turn that X to a 5 just like the other x which equals 5 as well...

but here's the catch when you times our X by 5 to equal 5 we are also going to times our Y by 5 to and do you know what 15 times 5 is it's 75.

now that we know that let's type that out to make it clear:

x=5 and y=75

you see the pattern now ;)

its 50 miles away from the starting point
