The formula we use is
Speed = distance /time
or
distance = speed * time
here in this question we are provided with speed = 52 mph
and distance = 286 miles
Now formula
distance = speed * time
286 miles = 52 mph * time
divide both sides by 52
286 /52 hours = time
time = 5.5 hours
or we can also say
5 hours 30 minutes
