A car and a van started travelling from Town X to Town Y at the same time. The distance between the two towns was 225 km. Both vehicles did not change their speed. The car arrived at Town Y 3/4 h earlier than the van. When the car reached Town Y, the van was still 45 km away from Town Y. What was the speed which the car was travelling?
Solution
(Van) speed -----
45 km divided by (3/4) h
= 60 km/h
(Van) time for the whole journey -----
225 km divided by 60 km/h = 3 and 3/4 hours
Therefore, the car travelled in 3 h.
Speed of car -----
225 km divided by 3 h = 75 km/h
Answer: 75 km/h
