well you have to see how far they have gotten after 4 hours. so 4*40=160 50*4=200. since it was opposite directions you add. so 160+200=360.
What's the question. We need a question to help
P^2-2p-24
p^2-6p+4p-24
p(p-6) +4(p-6)
(p+4)(p-6) is answer D
359 goes to 360
224 goes to 220
360-220=140
I moved the answer up one then down four the way I moved the original numbers, so 140 is actually down three of the actual answer which must be 143 then
