Question

Debbie flew from Seattle to San Diego with a stop in San Francisco to switch planes. Her first flight left Seattle at 11:35 A.M. and was 1 hour and 30 minutes long. Debbie was in San Francisco for 1 hour and 40 minutes, and her flight from San Francisco to San Diego was 1 hour and 20 minutes long. What time was it when Debbie landed in San Diego?

a) 2:25 P.M.
b) 3:15 P.M.
c) 3:55 P.M.
d) 4:15 P.M.

Answer 1

After calculating the durations Debbie spent in flight and during layovers, Debbie would have landed in San Diego at 4:05 P.M., which suggests a potential typo in the given options. The closest option provided is (d) 4:15 P.M., which might account for slight delays or rounding.

Step-by-step explanation:

To calculate what time Debbie landed in San Diego, we need to add up all the durations of her journey segments from Seattle. Debbie's first flight was 1 hour and 30 minutes long. So, if she left Seattle at 11:35 A.M., she arrived in San Francisco at:

11:35 A.M. + 1:30 = 1:05 P.M.

Debbie was in San Francisco for 1 hour and 40 minutes, so she would have departed San Francisco at:

1:05 P.M. + 1:40 = 2:45 P.M.

The flight from San Francisco to San Diego was 1 hour and 20 minutes long. Thus, Debbie landed in San Diego at:

2:45 P.M. + 1:20 = 4:05 P.M.

However, this option is not given in the choices, so we should check our calculations. Notice that when adding the time of 1 hour and 20 minutes to 2:45 P.M., we must account for the fact that adding 60 minutes would take us to 3:45 P.M., and then adding another 20 minutes puts us at 4:05 P.M.

Hence, the correct landing time would be 4:05 P.M., which might suggest a typo in the multiple-choice options provided. Option (d) 4:15 P.M. could be closest to the correct answer, assuming a minor delay or rounding in the actual flight timings or in the provided options.
