Explanation:

The truck does 3 sides of the square 3 x 24 = 72

and the truck does one entire diagonal of the square

with side lengths 24

diagonal = sqrt (24^2 + 24^2 ) = 33.94 miles

total miles 33.94 + 72 = 105.94 miles in 4.5 hours

105.94 / 4.5 = 23.54 m/hr for the entire trip

The mph for the actual driving time (2.5 hours )

105.94 / 2.5 = 42. 38 m/hr for driving time only
