Question

Keisha knows that trains arrive regularly at the train station. She has part of the afternoon schedule. When will the next train arrive at the station?

Answer 1

Answer: The next train will arrive at 4:46 P.M.

Solution:

The trains arrive regurlaly. We can find the minutes between arrivals substracting two consecutive arrivals:

4:02 P.M. - 3:40 P.M. = 22 minutes or

4:24 P.M. - 4:02 P.M. = 22 minutes

Then the next arrival is in 22 minutes:

4:24 P.M. + 22 minutes = 4:46 P.M.
