Answer 2

Answer:

0.443 hours

Explanation:

Given following:

• speed: 112.9094 mph

• distance: 50 miles

Formula:

$\sf time \ taken = \dfrac{distance}{speed}$

Substitute values to find time taken:

$\sf \rightarrow time = \dfrac{50}{112.9094 }$

evaluate

$\sf \rightarrow time = 0.4428329262$

rounded to nearest thousandth

$\sf \rightarrow time = 0.443$
