A motorist took a total of 4hr to drive from town A to town C. He took 1hr to travel from town A to town B,which is between town A & town C. The distance between town B & town C is 11/15 of the distance between town A and town C. If the total distance travelled is 360km,find the motorist's speed for the journey from town B to town C
AC = 360km.
BC = (11/15)360 = 264 km.
Speed=d/t = 264km / (4-1)hr = 88 mi/hr.
