Number of days Adya took to complete the work = 20
Work done by Adya in 1 day = 
Number of days Ashley took to complete the work = 25
Work done by Ashley in 1 day = 
So,
Total work by Adya & Ashley in 1 day =
•°• Their total work in 10 days =
Now,
The work left to be completed =
From this we know that,
Amber completes 
of the work in 3 days.
So,
Time taken by Amber to complete the whole work =
↦ If Amber alone would do the whole work, he would take

Step-by-step explanation:
Answer:
...
against the wind, an airplane travels 3640 km in 7 hours.
with the wind, the same plane travels 6000 km in 6hrs.
...
let speed of plane in still air be x mph
speed of wind be y mph.
..
t=d/r
..
against wind speed = x-y mph
with wond speed = x=y mph
...
3640/(x-y)=7
3640 = 7x-7y
/7
520=x-y.....................1
...
6000/x+y = 6
6000 = 6x+6y
/6
1000=x+y.....................2
...
Add (1) & (2)
2x=1520
/2
x=760 mph speed of plane in still air
...
plug value of x in 2
1000=760+y
100-760=y
240 = y
240 mph speed of wind
