The family home is 130KM from Cape town international Airport where they will catch their plane. They must be at the Airport 2hour's before the departure time. If they must maintain an average speed of 110km/h from home to the Airport,What is the latest time they will have to leave home in order to be on time?Round your answer to the nearest minutes .The formula may be used Speed =Distance ÷Time
To find the latest time they will have to leave home, we first need to determine the time it will take to travel 130km at an average speed of 110km/h.
Time = Distance ÷ Speed
Time = 130km ÷ 110km/h
Time = 1.18 hours
Since they need to be at the airport 2 hours before departure, we need to add 2 hours to the travel time.
Total time = 1.18 hours + 2 hours
Total time = 3.18 hours
Now, we need to convert the total time to minutes.
3.18 hours x 60 minutes = 190.8 minutes
Therefore, the latest time they will have to leave home in order to be on time is approximately 190.8 minutes before their flight departure time. This can be rounded to 191 minutes before departure time.
So, they will have to leave home approximately 3 hours and 11 minutes before their flight departure time to be on time.
