When running a 100 meter race alex reaches his maximum speed when he is 45 meters from the starting line, and 5 seconds have elapsed since the start of the race. alex continues at this max speed for the rest of the race and is 90 meters from the starting line 10 seconds after the start of the race.
what is alex's max speed?
suppose alex runs for an additional 2 seconds after reaching his max i. how far will alex travel during those 2 seconds?
what is alex's distance from the starting line 8 seconds after the start of the race?
what is alex's distance from the starting line 7.5 seconds after the start of the race?
