Question

a swimmer swam 0.8 mi at 0.0321 mi per min in waters created by melted sea ice. What was his time?

Answer 1

0.0321 miles per minute, simply means, in 1 minute, it does 0.0321 miles.

$\bf \begin{array}{ccll} miles&minutes\\ \cline{1-2} 0.0321&1\\ 0.8&x \end{array}\implies \cfrac{0.0321}{0.8}=\cfrac{1}{x}\implies 0.0321x=0.8 \\\\\\ x=\cfrac{0.8}{0.0321}\implies x\approx 24.92211838$

Answer 2

Remark

He's very lucky to be alive.

Givens

distance = d = 0.8 miles

Rate = r   =       0.0321 mi per minute

Time = t = ??

Formula

d = r * t

Solve

0.8 = 0.0321 * t      Divide by 0.0321

0.8/0.0321 = t

t = 24.92 minutes  <<<< Answer
