Answer:

d = (1/20) t + 2

Step-by-step explanation:

∵ The equation of Monika is:

  d = (1/15)t + 1 ⇒ linear equation

∴ The slope of the line = 1/15 ⇒ speed of Monika

∵ The speed of Mark is 3/4 as fast as Monika

∴ The speed of Mark = 3/4 × 1/15 = 1/20

∵ Mark starts a mile behind her

∵ at t = 0 ⇒ her distance is 1

∴ at t = 0 ⇒ his distance is 2

∴ His equation is d = (1/20) t + 2
