Recall your d = rt, distance = rate * time.
now, let's say she lives "d" miles away, and so if Billy goes say at "r" mph fast to her house, he gets there in 1hr.
now, if he goes 20 mph slower, namely " r - 20 " mph, he gets there in 2 hours, same "d" miles.
It would be =-5f
Hope this helps
20=2*10
500=5*10*10
20*500=
2*10*5*10*10=
2*5*10*10*10=
10*10*10*10=

= πr²
= (12)²
= 452.38934 inches²
452.38934 ÷ 16 = 28.27433 inches²
≈.28 inches² (nearest square inch)
the answer is 2.456
