I need more information about the dimensions of the barn
What's the question being asked here?
C. Is try correct answer
See example in the attached picture
It would be 20*7 which will give you 140 miles in 7 hours
We know that 3/10*20=6 students are eating salads.
We also know that 3/5*20=12 students are eating sandwiches.
Assuming each person only eats one thing, there are 20-12-6=2 students eating lunches other than salads or sandwiches.
