Answer:
The average speed is 51.43 miles per hour
Step-by-step explanation:
The average speed is defined as the time rate of change of distance, that is average speed is the ratio of distance to time. The average speed is given by the equation:
[tex]Average speed(s)=\frac{distance(d)}{time(t)} \\s=\frac{d}{t}[/tex]
Given that:
distance(d) = 60 miles and time (t) = [tex]1\frac{1}{6}[/tex] hours = 1.167 hours
Substituting values:
[tex]s=\frac{d}{t}=\frac{60}{1.167} =51.43[/tex]
The average speed is 51.43 miles per hour
Answer:
The average speed of the sales representative must be 51.43 miles per hour.
Step-by-step explanation:
The average speed is computed by dividing the distance that was travelled by the time that it took to get there. In this case the to complete the route was 1 1/6 = 6/6 + 1/6 = 7/6 hours and the distance is 60 miles, so we have:
v = distance/time = 60/(7/6) = 60*(6/7) = 360/7 = 51.43 miles per hour
The average speed of the sales representative must be 51.43 miles per hour.
