Law of sines:
$\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}\\=\frac{640}{\sin 70}=\frac{c}{\sin (180-70-52)}\\\text{ then}\\c=\frac{640}{\sin 70}\sin (180-70-52)\\=577$

It takes a turtle 3 1/4 hours to walk 1 1/2 miles how many hours does it take to walk one mile (show the work please)

Sliva [168]

Answer:

2 1/6 hours.

Step-by-step explanation:

It walks 1 1/2 miles in 3 1/4 hours.

So it walks 1 mile in (3 1/4 ) / (1 1/2) hours.

= 13/4 / 3/2

= 13/4 * 2/3

= 26/12 hours

= 2 1/6 hours.
