No idea why you question ended up in English subject. Here is the solution:

110 yards = 0.0625 miles

1 minute = 1/60 hours

Speed = 0.0625/(1/60) = 3.75mph (A)

2)

1 oz = 28.35g

15oz = 28.35 * 15 = 425.25g

453.6g = 1lb

793.8g = 1 * (793.8/453.6) = 1.75lb (D)

3)

82 = 18.5% of x

82 = 0.185x

x = 82/0.185 = $443.24 (B)
