We know that
average speed=distance/time
in this problem
distance=500 m
time=1.6 minutes
so
average speed=500/1.6------> 312.5 m/minutes
convert to m/sec
312.5/60-----> 5.21 m/sec
the answer is
the average speed is 312.5 m/minutes or 5.21 m/sec
Answer:

Step-by-step explanation:
I think you wrote the equations incorrectly. It probably is
If that is true, then 
0 = -16
+ 144t
-16t(t - 9) = 0
t = 0 or t = 9
