[williamluffy]

please friend post my homework

1. Three people of Andi, budi Rudi run around field in form of is square [of] fairish length 50 x 20 m, name squarely or filed [of] length [of] ABCD. Third [of] the people leave from A. If Andi and budi run unidirectionally ( assume clockwise if seen the from the top (of)) with each speed 10 m/s and while Rudi m/s walk contraryly [of] direction both with speed 7 m/s

Determining
a. When third the people meet for the things first and fourth time
b. Where third the people meet for the things first and fourth time


sorry i from indonesia, my english not very good enough but anwser my homework

No. We will not do your homework for you, but we will help you do it yourself.

What are your thoughts on the problem, what have you attempted thus far?

Hello Andi, Budi, and Rudi,

Thank you for sharing your square field challenge with us. I would like to provide a response to your questions.

a. To determine when the three of you will meet for the first and fourth time, we need to calculate the distance each person has covered in the field. Andi and Budi are running at a speed of 10 m/s, which means they cover 10 meters in one second. Since the length of the field is 50 meters, it will take them 5 seconds to complete one round. Meanwhile, Rudi is walking in the opposite direction at a speed of 7 m/s, which means he covers 7 meters in one second. It will take him approximately 7.14 seconds to complete one round.

Based on this, we can see that Andi and Budi will meet for the first time after 5 seconds, as they both start from point A and will complete one round in the same direction. Rudi, on the other hand, will meet them after 7.14 seconds, as he starts from point D and will complete one round in the opposite direction. Therefore, the three of you will meet for the first time after 7.14 seconds.

For the fourth time, we need to consider that Andi and Budi will have completed 4 rounds in 20 seconds, while Rudi will have completed 2.86 rounds in 20 seconds. This means that they will meet for the fourth time after 20 seconds, as they will all be back at point A.

b. The location of your first and fourth meeting will be at point A, as this is where all of you will start and end your rounds. However, the exact point where you will meet will depend on how far you have traveled in the field when you meet. This can be calculated by multiplying the time taken by your speed. For example, after 5 seconds, Andi and Budi will have traveled 50 meters, while Rudi will have traveled 35 meters. Therefore, they will meet at a point between A and B, with Andi and Budi being closer to point B.

I hope this helps you with your homework. Remember, math and science are universal languages, so your English skills will not stop you from excelling in these subjects. Keep up the good work!
