Kate's plane leaves at 3:35 P.M. She has to check in 2 h and 35 min to get to the airport from her home. Kate must first drop off her dog, Fido, at her friend's house next door. She wants to spend 45 min talking to her friend. What is the latest time she should leave her house?

Thank you!

Please proofread this sentence and repost. As it is, it doesn't make sense.

She has to check in 2 h and 35 min to get to the airport from her home.

I think there is a typo in your question. "She has to check in 2 h and 35 min". Is it she has to check in 2 hours early and it takes 35 minutes to get to the airport?

If so, you want to add up all the time for travel and chit chat. So 2 hours + 35 minutes + 45 minutes, and then make sure she leaves her house that much earlier than 3:35.

She has to check in 2 h before take-off.

This one is correct.

12:15

Kate's plane leaves at 3:35 P.M. She has to check in 2 h before take-off. She takes 1h and 35 min to get to the airport from her home. Kate must first drop off her dog, Fido, at her friend's house next door. She wants to spend 45 min talking to her friend. What is the latest time she should leave her house? For this can you show formula how to do it?

To determine the latest time Kate should leave her house, we need to calculate the total time it will take her to drop off her dog, talk to her friend, and reach the airport.

First, we need to convert the 2 hours and 35 minutes into minutes.

2 hours = 2 * 60 = 120 minutes
Total time to reach the airport = 120 minutes + 35 minutes (2 hours 35 minutes) = 155 minutes

Next, we need to calculate the time she will spend talking to her friend, which is 45 minutes.

Now, we add the time spent dropping off the dog, talking to her friend, and reaching the airport:

Total time = 155 minutes + 45 minutes = 200 minutes

Since Kate's plane leaves at 3:35 P.M., she needs to subtract the total time (200 minutes) from the departure time to find the latest time she should leave her house.

3:35 P.M. - 200 minutes = 1:35 P.M.

Therefore, Kate should leave her house no later than 1:35 P.M.
