Respuesta :

Add 45 to X (?h) and 2mi to 1mi. It should look like this:
45min + X = 3mi
next you subtract 45 on both sides and get X = -42


hope this helps :)
Your answer for ? is 22.5 or 22 1/2

To solve this you would cross multiply
45 x 1 = 45
2x = 2x

Then, you would divide those by 2

2x/2 = x
45/2 = 22.5

Finally, I would convert the 22.5 minutes into hours by dividing 22.5 and 60

22.5/60
= .375 h

And there's my answer! :)
