To find the average speed for the whole race, you just have
to add the speed from a starting marker and the speed from the turnaround
marker going back and divide it by 2 since there are only two speeds involved.
10 m/s + 16m/s = 26 m/s / 2 = 13 m/s
Therefore, the average speed for the whole race is 13 m/s.
42. Because you divide into 6 and 7. 6 is divided into 3 and 2. So, 2 times 3 times 7.
True, every number is a complex number.
I hope this helps. :)
The correct answer is the 3rd option !! good luck
