A car was on its way from Town V to Town W. After covering ³₅ of its journey, it passed a van which was travelling at an average speed of 66 km/h. 10 hours later, the car reached its destination, but the van was still 26 km from Town W. If the car had also started from Town V, how long would it take to travel from Town V to Town W? Express your answer as a mixed number.
Fraction of the journey left after the car passed the van
= 1 - ³₅
= ²₅

²₅ of the car's journey = (10 x 66) + 26 = 686 km
¹₅ of the car's journey = 686 ÷ 2 = 343 km
⁵₅ of the car 's journey = 5 x 343 = 1715 km

Speed of the car
= 686 ÷ 10
= 68.6 km/h

Time taken for the car to reach Town W
= 1715 ÷ 68.6
= 25 h

Answer(s): 25 h
