Question 426490
You just need to express 4 hrs 41 min in terms of hours. Then
you will have an answer in miles/hour
The simplest expression, since 41 has no divisors is
{{{ 4 }}} hours + {{{41/60}}} (min/(min/hr) =
{{{ 240/60 + 41/60 = 281/60 }}} hrs
{{{ 281 / (281/60) = 60 }}} 
The average speed is 60 mi/hr
Note that {{{240/60}}} is not a conversion, it
is just another way to express {{{4}}} hrs
