Answer:
70 minutes
Step-by-step explanation:
3 1/2 ÷1/4= 14 ×5= 70
so you first make 3 1/2 to an improper fraction, then you find the greatest common denominator between 7/2 and 1/4 which is 4, so you multiple 7/2 by 2 and get 14/4 and divide that by 1/4 and get 14minutes now multiply that by 5 laps and receive 70 minutes.
For 12, you would do 90=4x+42, and 48=4x, and x=12
for 15, you would do 90=8x+66, and 24=8x, and x=3
for 18, you would do 90=3x+57, and 33=3x, and x=11

I think the answer is C.
I figured this out because if they asked 12 people and 8 thought that their boss is understanding and 96 people work there I figured they asked 1/8 of the workers and 4/6 thinks he is an understanding person.
96 divided by 12 = 8
96 divided by 6 = 16 and 16 x 4 = 64
Hope this helps.
