Question

Brylee has hiked 125 feet and hikes 1 foot per second. Jeremiah has hiked 10 feet and hikes 3.5 feet per second. After how many seconds will Brylee and Jeremiah have hiked the same amount of feet?

Answer 1

46 seconds

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
