Question

Jason and Sheldon are neighbors who work for the same accounting firm. They leave the office at the same time. After t seconds, Jason's distance from the office in meters is given as 4 more than 3 times t, while Sheldon's distance from the office is 6 more than 2 times t. The function that represents the total distance d(t) that Jason and Sheldon cover together in t seconds is given by d(t) = . In 7 seconds, Jason and Sheldon together cover a distance of meters.

Answer 1

d(t) = (3t+4) + (2t+6), so d(7) = (3*7) + 4 + (2*7) + 6 = 21 + 14 + 10 = 45
