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* When the car reached Town Y, the van was still 45 km away. The car arrived at Town Y 3/4 h earlier than the van.
(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/hPrinter Friendly Version
