Eddy and Freddy start simultaneously from city A and they travel to City B and City C respectively. Eddy takes 3 hours and Freddy takes 4 hours to complete the journey. If the distance between City A and City B is 600 kms and City A and City C is 360 kms. What is the ratio of their average speed of travel? (Eddy: Freddy)
Choices
A) 8 / 3 B) 3 / 8 C) 8 / 5 D) 5 / 8 E) 20 / 9

Rationale: "distance traveled by eddy = 600 km time taken by eddy = 3 hours average speed of eddy = 600 / 3 = 200 km / hour distance traveled by freddy = 360 km time taken by freddy = 4 hours average speed of freddy = 360 / 4 = 90 km / hour ratio of average speed of eddy to freddy = 200 / 90 = 20 / 9 answer e"
Answer: E
