John drove for 1 hours at a rate of 90 miles per hour and for 2 hours at 60 miles per hour. What was his average speed for the whole journey?
[Double click if you get it the first time that you play this game]
Average distance is 90 + 120 = 210 miles
Average time is 1 + 2 = 3 hrs
210 divided by 3 = 70 m/hr

What is the distance over which a wave's shape repeats?
wavelength
