Susan drove to visit a friend. She drove 345
padilas [110]

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
