Question 670517
<font face="Times New Roman" size="+2">


Let *[tex \LARGE t_1] represent the elapsed time for the first leg of the trip.  Calculate the value of *[tex \LARGE t_1] by dividing the distance of the first leg by the speed of the first leg.  Likewise, calculate *[tex \LARGE t_2], the elapsed time for the second leg, by dividing distance by speed.  Note, you are not given the distance of the second leg directly; you must calculate by subtracting the distance of the first leg from the total distance of the trip.


Once you know the elapsed time for each leg of the trip, you can calculate the total time for the trip by adding the two times you just calculated.  The average speed for the entire trip is the total distance divided by the total time.

My calculator said it, I believe it, that settles it
