It would take 5 hours for all the bacteria to die. 1000 divided by 5 is 200 so 200x5=1000
Here is the set up:
Side 1 is 4x.
Side 2 is 5x + 3
Side 3 is 5x + 1
The perimeter is 102.
Perimeter = side 1 + side 2 + side 3
102 = 4x + 5x + 3 + 5x + 1
102 = 14x + 4
Take it from here.
5 miles because 2 miles then add 3 miles equals 5 miles
