(1) A motorist traveled along a straight road from town A to town B at 70 km/h.
(2) A motorcyclist traveled from town B to town A at 80 km/h.
(3) Both started the journeys at the same time and traveled on the same road.
(4) a) If they passed each other after traveling for 1 hour and 40 minutes, find the distance between town A and B.
(5) b) How long did the motorcyclist take to travel his whole journey?

Your post was formulated quite inaccurately.
So I rewrote it to make everything clear.
a) The distance between town A and B = = = = 5*50 = 250 kilometers. ( = hours = 1 hour 40 minutes)
b) How long did the motorcyclist take to travel his whole journey = = = hours = 3 hours 7.5 minutes.
