Hi. This is a bit lengthy so I am attaching an image that shows it worked out step by step. I hope it helps.
Take care,

It’s beautiful because if you set up the problem as proportion and you put 3/106 over to you would have to multiply by 2×3 to get a six and 1×2 to get it to so it’s 2 mph
Depends is the positive integer is larger than the negative interger for example -10+5=-5.
10+-4=6
