Rachel is a stunt driver, and she's escaping from a building that is about to explode! D represents Rachel's remaining distance (in meters) after t seconds. D=-38 t+220 How long is the distance Rachel has to drive? ◻ meters

Equation for Rachel's Distance: We have the equation for Rachel's remaining distance D after t seconds: D = -38t + 220. To find out how long the distance Rachel has to drive, we need to find out when D equals 0.Set Equation to 0: Set the equation to 0 and solve for t: 0 = -38t + 220.Add 38t: Add 38t to both sides: 38t = 220.Divide by 38: Divide both sides by 38 to solve for t: t = 220 / 38.Calculate Final Time: Calculate t: t = 5.78947368421. Oops, we need a whole number for the seconds, so we round down to the nearest whole number, t = 5 seconds.

Equation for Rachel's Distance: We have the equation for Rachel's remaining distance $D$ after $t$ seconds: $D = -38t + 220$ . To find out how long the distance Rachel has to drive, we need to find out when $D$ equals $0$ .
Set Equation to $0$ : Set the equation to $0$ and solve for $t$ : $0 = -38t + 220$ .
Add $38t$ : Add $38t$ to both sides: $38t = 220$ .
Divide by $38$ : Divide both sides by $38$ to solve for $t$ : $t = \frac{220}{38}$ .
Calculate Final Time: Calculate $t$ : $t = 5.78947368421$ . Oops, we need a whole number for the seconds, so we round down to the nearest whole number, $t = 5$ seconds.
