Your family is planning a 4-h car trip. Along the way you are planning to make three 1/2 h stops. At what time should you leave home to arrive at the destination by 8:00 p.m.?
how would I do this?
4 + 1 1/2 = 5 1/2 hours
Subtract 5 1/2 hours from 8 p.m.
I'll be glad to check your answer.
2:30 p.m?
Right.
To determine the time you should leave home to arrive at the destination by 8:00 p.m., you need to consider the total travel time, the duration of stops, and the desired arrival time.
Here are the steps to calculate the departure time:
1. Calculate the total travel time: Since you have three 1/2 hour stops, the total duration of stops is 3 * 1/2 hour = 1.5 hours.
2. Subtract the duration of stops from the desired arrival time to find the total travel time: 8:00 p.m. - 1.5 hours = 6.5 hours.
3. Add the total travel time to the duration of stops to get the total trip duration: 6.5 hours + 1.5 hours = 8 hours.
4. Subtract the total trip duration from 8:00 p.m. to find the departure time: 8:00 p.m. - 8 hours = 12:00 p.m.
Therefore, you should leave home at 12:00 p.m. to arrive at your destination by 8:00 p.m.
