13 mph
using d=rt you can set up 2 equations
48=(r+3)t
30= (r-3)t
solving these both for t and setting them equal warrants
48/(r+3) = 30/(r-3)
and with cross multiplication and distribution you get
48r-144=30r+90
solving for r you get r=13
X=4 because if you do 4 times 4 and 10^32 power you would then subtract that and that would then be you answer<span />
