louise walked past thurman at a speed of 2 feet per second. After 5 seconds, thurman started after her at a speed of 4 feet per secon.d how many seconds did it take thurman to catch louise?
First, we need to find out how far Louise has walked in 5 seconds:
Distance walked by Louise = Speed * Time
Distance walked by Louise = 2 feet per second * 5 seconds
Distance walked by Louise = 10 feet
Now, Thurman starts walking towards Louise at a speed of 4 feet per second. Since he is starting from a distance, he needs to cover the 10 feet that Louise has already walked before he can catch up.
Time taken by Thurman to catch up = Distance / Speed
Time taken by Thurman to catch up = 10 feet / 4 feet per second
Time taken by Thurman to catch up = 2.5 seconds
Therefore, it will take Thurman 2.5 seconds to catch up to Louise.
incorrect
Let's correct the solution:
Since Louise walked past Thurman at a speed of 2 feet per second for 5 seconds, she would have traveled a distance of 2 feet/s * 5 s = 10 feet.
When Thurman starts walking at a speed of 4 feet per second, he needs to cover that 10 feet distance to catch up to Louise.
Time taken by Thurman to catch up = Distance / Speed
Time taken by Thurman to catch up = 10 feet / 4 feet per second
Time taken by Thurman to catch up = 2.5 seconds
Therefore, it will take Thurman 2.5 seconds to catch up to Louise. Thank you for your patience.
incorrect, the answer is not 2.5 seconds
Apologies for the confusion. Let's reevaluate the solution:
Louise walked past Thurman at a speed of 2 feet per second for 5 seconds, covering a distance of 2 feet/s * 5 s = 10 feet.
When Thurman starts walking at a speed of 4 feet per second, he is initially 10 feet behind Louise. To catch up, he needs to close this 10-foot gap.
Time taken by Thurman to catch up = Distance / Relative speed
Time taken by Thurman to catch up = 10 feet / (4 feet per second - 2 feet per second)
Time taken by Thurman to catch up = 10 feet / 2 feet per second
Time taken by Thurman to catch up = 5 seconds
Therefore, it will take Thurman 5 seconds to catch up to Louise. Thank you for your patience, and I appreciate the correction.
