Answer
$298.26$
Work Step by Step
The given expression is
$=\frac{8\; km}{min}$
$1 \;km = 0.621371\; mi$
Multiply each side by $8$.
$8\times 1 \;km =8\times 0.621371\; mi$
Simplify.
$8 \;km =4.97097\; mi$
$1\;min=\frac{1}{60}\;h$.
Substitute both the values into the given expression.
$=\frac{4.97097\; mi}{\frac{1}{60}\;h}$
Simplify.
$=\frac{298.26\; mi}{h}$
Hence, the correct fill in the blank is $298.26$.
