S = 2b + ph
Lets subtract both sides by 2b
s - 2b = ph
Now, divide both sides by h
(s-2b)/h = p
Hope this helps!
10-4 =6
14x10= 140
50+49= 99
49x10=490
So first of all you'd want to convert the miles to yards. So 139 miles is 244640 yards. Then you'd have to divide that by 3600, because that's how many seconds are in an hour. This is about 68 yd/s
