Answer:
46 seconds
Step-by-step explanation:
Brylee has hiked 125 feet and hikes 1 foot per second.
125 + s
Jeremiah has hiked 10 feet and hikes 3.5 feet per second.
10 + 3.5s
Where
s = number of seconds
Equate both Brylee and Jeremiah expression
125 + s = 10 + 3.5s
Collect like terms
125 - 10 = 3.5s - s
115 = 2.5s
Divide both sides by 2.5
s = 115 / 2.5
= 46
s = 46 seconds
