Answer:
33993.0768
Step-by-step explanation:
You can multiply the number of bacteria by (0.2^4). The 0.2 is for the 20% that left after each day. The (^4) is for the 4 days that have passed.
4/5x + 4/3 = 2x....there are 2 ways to do this...one with fractions, one without.
with :
4/5x + 4/3 = 2x
4/3 = 2x - 4/5x
4/3 = 10/5x - 4/5x
4/3 = 6/5x
4/3 * 5/6 = x
20/18 = x
10/9 = x
without :
4/5x + 4/3 = 2x....multiply by common denominator of 15
12x + 20 = 30x
20 = 30x - 12x
20 = 18x
20/18 = x
10/9 = x
Answer:
= 50 Minutes
Whole Race Time : 2 Hour and 50 Minutes
Step-by-step explanation:

.
200 divided by 4 = 50
so Holden still need 50 Minutes to finish the race.
