Atraveler is walking on a moving walkway in an airport. the traveler must walk back on the walkway to get a bag he forgot. the traveler's ground speed is 1 ft/s against the walkway and 7 ft/s divided by s with the walkway. what is the traveler's speed off the walkway? what is the speed of the moving walkway?

let t = traveler's normal walking speed
let w = walkway speed

Write an equation for each scenario
t - w = 1

t + w = 7

 t=1+w

(1+w)+w=7

1+2w=7

w=3 ft/s walkway speed

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221
