In the question there are numerous information's of immense importance already given. Let us write them down first Distance traveled by bike = x km Distance traveled by bus = y km Total distance traveled by George and Carmen = 325 km Then x + y = 325 Another equation can be determined by x - y = 75 x = y + 75 Now we will put the value of x in relation to y in the first equation. x + y =325 y + 75 + y = 325 2y = 325 - 75 2y =250 y = 250/2 = 125 km Now putting the value of y in equation given below, we get x + y = 325 x + 125 = 325 x = 325 - 125 = 200 km So the distance they biked is 200 km and the distance they traveled by bus is 125 km.
