Answer:

#v = 68.61 (mi)/(hr)#

Explanation:

Displacement = velocity x time

#DeltaX = v*t#

Therefore

#(DeltaX )/t= v#

First we change the minutes to the necessary units hours by division

#35min* (1 hr)/(60min) = 0.583 hr#

#Delta X = 40 mi#
#t= 0.583 hr#
#v=?#

#(40 mi)/(0.583 hr) = v#

#v = 68.61 (mi)/(hr)#
