let the trip be of &#039;x miles&#039;long.Angela made the trip by bus in 16 hrs.so speed of bus = (x/16) miles/hrAngela made the return trip by car in 20hrs.so, speed of car = (x/20)miles/hrgiven that, the bus traveled 10 miles perhr faster than the car.so,  x/16 = x/20 +10=&amp;gt; x/16 - x/20 =10 [changing sides]=&amp;gt; (5x - 4x)/80 =10 [doing L.C.M. on left hand side]=&amp;gt; x / 80 = 10=&amp;gt; x =800 [cross multiplication]Answer:- the trip was 800 miles long

it was 800 miles16 times x = 20 times y,     x and y = themphdivide by 16 by 20 and y by x16/20 = y/x    simiplify4/5 = y/x x=5 and y=4multiply x or y by 10 then multiply your answer by 16 or 20 and that is 800 which is the answer
