Answer:
A. 43
Step-by-step explanation:
So this is an algebra question, where you have have to setup the equation. Let t represent the number of hours.
36 + 8.80t < 115.20 we can then setup the equation like this to solve for the max hours.
36 + 8.80t= 115.20
Now solve
8.80t = 115.2-36
8.80t= 79.2
t = 9
so t < 9
The distance of the cruise liner from me 20 seconds later will be; 2600ft.
<h3>How far will the cruise liner be in 20 seconds?</h3>
a) Since, the speed of the liner is 30ft/sec, it follows that after 20secs, the liner would cover; (30×20)ft = 600ft more; and consequently, the distance is now; √(2000²+600²) = ft.
b) For the boat to be 2500 ft away given the speed 30ft per sec; Time taken = 2500/30 = 83.3seconds. Hence, the boat will be more than 2500 feets away after 2 minutes.
c) If the boat's distance is 2000ft from me; it follows that the distance covered is 10 seconds is; √(2000²-1500²) = 1322.9ft
Hence, the speed to attain this distance is; 1322.9/10 = 132.29ft/sec.
