one car is traveling at 55 kilometers per hour the other is at 70let x = speed of first car=> speed of second car = x+15knowing that the total milage covered in 4 hours was 500 Kmx+(x+15) = 500/42x + 15 = 1252x = 110x = 55=> car one is 55 Kph=> car two is 70 Kphto check work, in 4 hours, car one travels 55 * 4 Km => 220 Kmcar two travels 70 * 4 Km => 280 Km220 + 280 = 500 Km
