Hey hey!
56 would be the answer.
WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.
Here’s how I got the answer:
7:4 walls = 10:8 people =M:40 minutes
M = (7/4) / (10/8) x 40
M = 56 minutes.
If that helped let me know by hitting the thanks button or reply with any help you need.
Have a FABULOUS DAYYY!
