Answer:
Melinda will paint 5/8 part of a wall when Desiree has finished painting 1 wall.
Step-by-step explanation:
It is given that:
Melinda can paint 1/4 of a wall in the same time that Desiree can paint 2/5 of a wall.
Let 't' be the time taken by Melinda and Desiree to paint 1/4 and 2/5 of a wall respectively.
Now the time taken by Desiree to paint 1 wall will be:
2/5 of wall= t
1 wall= (5/2) t
Now in this time ( i.e. 5/2 t) the part of a wall painted by Melinda will be:
As Melinda takes-- t time to paint= 1/4 of a wall
5/2 t she will paint= (5/2)×(1/4) of a wall= (5/8) of a wall.
Hence Melinda will paint 5/8 part of a wall when Desiree has finished painting 1 wall.
