The shardze family is planning A car trip to Atlanta Georgia which is 279 miles from their home they plan to drive at an average speed of 62 mph they also plan to stop for lunch for 45 minutes based on their plan when should I leave in order to arrive in Atlanta at 3 o'clock

They are going 279 miles at a rate of 62 mph.

time = distance / speed

time = 279/62

time = 4.5 hrs ... or (4 hrs 30 minutes)

plus they plan on a 45 minute lunch ...

4 hrs and 30 minutes + 45 minutes = 4 hrs and 75 minutes =

5 hrs 15 minutes. So they need 5 hrs and 15 minutes to get there ... and they want to be there by 3.

So they will have to leave at : 9:45 <==
