Take the total distance (60km) divided by the speed (x which u found in part e) and that will be the time. D=SxT
*Make sure to add 10km/h to X forst before diving as you are finding Rueben's speed not Owen's!!!!!!)
*Make sure to add 10km/h to X forst before diving as you are finding Rueben's speed not Owen's!!!!!!)
Once you solve the equation, you'll get x=-15 and x=5. Negative value is rejected. Take x=5 and substitute in the Reuben speed which is (x+10)km/h. Ans 15kkm/h
