Question

Two siblings are racing. The older sibling can run at a constant speed of 11 feet per second. The younger sibling can run at a constant speed of 7 feet per second. If the younger sibling is given a 32-foot head start in the race, how long will it take the older sibling to catch the younger sibling, and how far will the older sibling have run at that moment?(1 point)

The older sibling will catch the younger sibling after ___ second(s) and running___feet.

Answer 1

8 seconds after running 88 feet

Step-by-step explanation: this is what it told me the answer was

Answer 2

The older sibling will catch the younger sibling after 8 second(s) and running 88 feet.

Explanation:

Older Sibling: 11ft 22ft 33ft 44ft 55ft 66ft 77ft 88ft

Younger Sibling: 32ft 39ft 46ft 53ft 60ft 67ft 74ft 81ft

The younger sibling started at 32ft because of the headstart. Each number was after 1 second. So this means it took 8 seconds for the older sibling to get to 88ft, and it took 8 seconds to get the younger sibling to 81ft.

I hope you can understand. :)
