Answer: 2.5 or 2 1/2

Step-by-step explanation:

You can convert the mixed fractions to decimal numbers:

- Divide the numerator by the denominator of the fraction.

- Add the result to the whole number.

Thenyou have:

Barbara's time: $3\ 3/10=3+0.3=3.3$

Donna's time: $2\ 4/5=2+0.8=2.8$

Cindy's time: $4\ 3/5=4+0.6=4.6$

Nicole's time: $2\ 1/10=2+0.1=2.1$

As you can see, the fastest girl is Cindy and the slowest girl is Nicole.

Then, you must make the following subtraction to calculate the difference:

$4.6-2.1=2.5$ or 2 1/2

H = 70ft.
P = 35ft.
B = ?

H^2 = P^2 + B^2
70×70 = (35×35) + B^2
B^2 = 4900-1225
B = √3675
B = 35√3 ft.
