Two buses going in opposite directions, one at 55mph, the other a 48mph. That means in 1 hr, the first bus would have traveled 55 mi and the second will have traveled 48 mi. 55+48=103mi apart. We can use this to set up our equation, with x being the number of miles traveled: 55x+48x=619
<span>55x+48x=619 </span> <span>103x=619 </span> <span>x=6 </span> <span>6 miles is your answer.
the sign would probably be a negative. imagine this - - - - - - and then + + +, cancel out the negatives and plus then you are left with more negatives than positive so the sign will take the negative sign.
