Question

There is Part A and part B

Answer 1

A:
$\frac{25}{19} = \frac{x}{1} \\ 19x = 25 \\ x = \frac{25}{19}$
he can swim 25/19 yards per sec

b:
$\frac{ \frac{25}{9} }{1} = \frac{y}{60} \\ \frac{25}{9} = \frac{y}{60} \\ 9y = 60 \times 25 \\ y = \frac{60 \times 25}{9} \\ y = \frac{1500}{9} \\ y = \frac{500}{3}$
he can swim 500/3 yards per min
