The answer is 2.6 m/s
The speed (v) is distance (d) through time (t).
v = d/t
We know:
d = 390 m
t = 150 s
v = d/t
v = 390 m / 150s
v = = 2.6 m/s
There will be 45,600 bacteria present after 19 hours
200×180 =36,000
36,000 / pi (approx 3.14)= 11,459.1559026
15.25 percent of 900 will be 137.25 just look it up on google
