1) Two ants race across a table that is 72.5 cm long. One travels at 4.02 cm/s and the other at 2.7 cm/s. When the first one crosses the finish line, how far behind is the second one? Answer in units of cm.
2) The position of a car coasting down a hill was observed at various times and the results are summarized in the table below.
a) Find the average velocity of the car during the first second. Answer in m/s.
b) Find the average velocity of the car during the last three seconds. Answer in m/s.
c) Find the average velocity of the car during the entire period of observation in m/s.
1. Time taken by 1st ant = 72.5/4.02 = 18 sec.
Distance traveled by 2nd ant in 18 sec = ...
