It takes a boat 2 hours to travel 24 miles downstream and 3 hours to travel 18 miles upstream. What is the speed of the boat in water still? What is the speed of the current of the river?

answer: this is not a question

step-by-step explanation: this is a answer

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

step-by-step explanation:

the answer is 89 d

i took the test

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
