Answer:

$Average\ Speed = 60 mi/hr$

Step-by-step explanation:

Given

$Distance = 345\ miles$

$Time = 5\ hours\ 45\ minutes$

Required

Determine the average speed

This is calculated as thus:

$Average\ Speed = \frac{Distance}{Time}$

Convert time to hour:

$Time = 5\ hours\ 45\ minutes$

$Time = 5\ hours + \frac{45}{60}\ hour$

$Time = 5\ hours + \frac{3}{4}\ hour$

$Time = \frac{20 + 3}{4}\ hours$

$Time = \frac{23}{4}\ hours$

$Time = 5.75\ hours$

$Average\ Speed = \frac{Distance}{Time}$

$Average\ Speed = \frac{345}{5.75}$

$Average\ Speed = 60 mi/hr$
