marina has 200 more books than ethel.marina gives 60% of his books to ethel.ethel then gives 25% of her books back to marina .in the end ,ethel has 200 more books than marina.how many books does marina have at first?

At first: M has 10U + 200, E has 10U
Step 1 - M give E 60%: M has 4U + 80, E has 16U + 120
Step 2 - E give M 25%: M has 8U + 110, E has 12U + 90

12U + 90 - 200 = 8U + 110
4U = 310 - 90 = 220
U = 55

Initially Marina has 550 + 200 = 750 books

T starts at point C
W starts at point F

T : W
1.5 : 1
3 : 2

Think of each side of the hexagon track as 1 unit.
Example:
1st Time
T: Point F
W: Point B

2nd Time
T: Point C
W: Point D

3rd time
T: Point F
W: Point F

(a) They will meet at point F.

Wilson ran for (6x0.5) km = 3 km
20 min for 3 km
60 min for 9 km
1.5x9 = 13.5 km/h

(b) Tommy's speed is 13.5 km/h.
