Alberto is at the top of a 1560 foot slope, with a height of 4600 feet, and a vertical drop of 600 feet. If he reached the bottom of a 1560 ft slope in 24 seconds, how far down would he be in 10 seconds?
Thank you for the opportunity to help you with your question! My name is Alan Cheng
Notice you are given three different lengths in the problem. You have a slope length of 1560 ft, a height length of 4600 ft., and a vertical drop length of 600 ft. The important length here is the 1560 feet.
The slope of 1560 feet is a slant height that has length of 1560 feet.
We assume his speed down the slope is constant due to friction which acts against gravity, with net force of zero. We assume Alberto started down the slope with his own velocity.
We take the proportion 1560/24 = x / 10 and solve for x Because we assume velocity is constant.
in solving, we get x = 15600/24 = 5200/8 = 650 feet
Therefore in 10 seconds, Alberto has traveled 650 feet down the slope.
Please let me know if you need any clarification. I'm always happy to answer your questions.
