An air traffic controller is tracking two planes. to start, plan a is at an altitude of 2172 feet and plan b is just taking off. plan a is gaining altitude at 35.25 feet per second and plan b is gainnig altitude at 80.5 feet per second. how many seconds will pass before the planes are at the same altitude? what will their altitude be when they're at the same altitude?

158.94 seconds

altitude is 12,794.61 feet

the answer is d

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
