Your itinerary is below. you receive the folowing messasge from a friend: " lets meet for dinner before you go back to the hotel. the restaurant is 25 minutes from the client's office. 12: 00pm -1: 00pm drive to client 1: 00pm- 2: 00pm prepare for meeting 2: 00pm- 5: 15pm meeting with client 5: 15pm- 6: 00pm drive to hotel what is the earliest time you can arrive at dinner?

the earliest you can arrive at the restaurant is 5:40 pm.

The message of your friend says "before you go back to the hotel" which means, according to your itinerary, after the meeting with the client.

Always according to your itinerary, the meeting with the client is expected to last until 5:15 pm, therefore that is the earliest time at which you can leave towards the restaurant.

The restaurant is "25 minutes from the client's office", therefore, the time of arrival at dinner is 5:15 + 25 minutes.

The time is given in the form hh:mm, therefore you need to add the minutes: 15 + 25 = 40.

Hence, the earliest you can arrive at dinner is 5:40 pm. 

Not sure what the question is?
