Answer:
Tom's share = €800
Step-by-step explanation:
Given that:
Amount shared by Al, Tom and Joe = €3000
Ratio of Al's share to Tom's share = 5 : 4
Joe's share = 1.5(Tom's share) = 1.5(4) = 6
Therefore,
Ratio of Al, Tom and Joe = 5 : 4 : 6
Let,
x be the number of times of amount each get.
5x + 4x + 6x = 3000
15x = 3000
Dividing both sides by 15

Tom's share = 4x = 4(200) = €800
Hence,
Tom's share = €800

Answer: 6.125 hour
Explanation:
Train 1 ===> 1 hour = 90 miles
Train 2 ===> 1 hour = 120 miles
