f you travel 5 mph for 2 hours and 55mph for 24 minutes.
what is your average speed
:
Since we are using mph, change 24 min to 24/60 = .4 hrs
:
Let a = average speed for the trip
:
Write a distance equation; Dist = speed * time
5(2) + 55(.4) = a(2+.4)
:
10 + 22 = 2.4a
32 = 2.4a
a = 32%2F2.4
a = 131%2F3 mph hr

Check this:
13.33* 2.4 = 32 mi
