Answer:
20 km/hr
Explanation:
time taken by the boat going upstream = 11 hours
time taken for downstream movement = 9 hours
speed of the current = 2 km/h
distance traveled by the boat = d
Assume the speed of boat be x
we know,
distance = speed × time
moving upstream
distance = speed × time
d = (x -2) × 11
downstream
d = (x+2) × 9
now
(x+2) × 9 = (x -2) × 11
2 x = 40
x = 20 km/hr
hence, the speed of the boat will be 20 km/hr
Ralph is the athletic, charismatic protagonist of Lord of the Flies.
The strong-willed, ego maniacal Jack is the novel’s primary representative of the instinct of savagery, violence, and the desire for power—in short, the antithesis of Ralph.
An overweight, intellectual, and talkative boy, Piggy is the brains behind many of Ralph’s successful ideas and innovations, such as using the conch to call meetings and building shelters for the group.
The only element among these that are to be used in a formal letter are complex sentences.
As a matter of fact, idioms, contractions, and cliches should be avoided because they are very informal.
