Answer:
50 seconds.
Step-by-step explanation:
Given:
Jerome starts at 50 meters east of the park gate
Noah starts at 57 meters east of the park gate
Walking speed of Jerome = 1.11 meters per second.
Walking speed of Noah = 0.97 meters per second
Both are walking in the same direction.
Question asked:
After walking for how many seconds will Noah and Jerome be side-by-side on the trail?
Solution:
Let time = [tex]t[/tex]
It is given that Jerome starts at 50 meters east of the park gate and Noah starts at 57 meters east of the park gate means distance covered by Jerome will be 7 meter more than Noah.
Distance covered by Jerome - Distance covered by Noah = 7
[tex]speed\times time - speed\times time = 7\\\\[/tex]
[tex]1.11\times t-0.97\times t = 7\\1.11 t-0.97 t = 7\\0.14t=7[/tex]
Dividing both sides by 7
[tex]t=50\ seconds[/tex]
Thus, after walking 50 seconds Noah and Jerome will be side-by-side on the trail.
