Answer 1

Kenneth ran a marathon (26.2 miles) in 5.5 hours.

What was Kenneth's average speed?

52.4/11

Answer: 4.8 mph

Answer 2

By definition, we have that the speed is given by:

$v = \frac{d}{t}$

Where,

d: distance traveled

t: time to travel said distance

Substituting values we have:

$v = \frac{26.2}{5.5}\\v = 4.763636364$

Then, rounding the obtained speed we have:

$v = 4.8 mph$

Answer:

Kenneth's average speed is:

v = 4.8 mph
