To find the unit rate in miles per hour, we need to divide the total distance traveled by the total time taken.

Given:

  • Distance = 813.5 miles
  • Time = 5 hours

The formula for the unit rate (miles per hour) is:

Unit Rate=DistanceTime=813.5 miles5 hours

Calculating that:

Unit Rate=162.7 miles/hour

So the correct answer is:

A: 162.7 miles/hr
