<span>The question is asking "which of the following suggestions can help you to start a job productively?" and there are options, so let's go through them:
A. Making your own rules will earn you respect. - this is not true, as your own rules might not be the same as rules of the company
B. Make a commitment to do the best job you can. - this is the best answer! It's impossible to do a job better than you can, but if you do it the best you can, typically you will be very, very good at it.
C. Dress the way you want, not the way coworkers do, so you'll stand out. - This is not true! dressing up does not have an influence on the job productivity, and it can make you be seen negatively at work
D. Asking others about productivity requirements is a sign of a poor employee. - asking others is usually good, it means you want to learn, so it should not be bad for you!</span>
D) sepals
other options are ridiculous
Answer : distance, d = 463.7 m
Explanation :
According to the given condition it can be assumed that the first echo would be heard from closest cliff. The second echo is from farther cliff and the third echo is from the reflection between the two cliffs.
Let the distance between the first cliff and the point of firing is x and y is the distance between the second cliff and the point of firing.
Then the first echo will travel 2x distance, second will travel 2y distance and third will travel 2x +2y.
So, using above data :
and
On solving :
x = 321.9 m and y = 141.8 m
Hence, total distance between two cliffs is d = 321.9 m + 141.8 m = 463.7 m
