Preston has to make four phone calls to clients today. The call to Mr. Miller will take about an hour to complete, the call to Ms. Winnecuit will take about five minutes to complete, the call to Mr. Drudge will take about thirty minutes and the call to Mrs. Freich will take about fifteen minutes to complete. If all the calls are equally important, who should Preston call first?
Answer
A
Mr. Miller (1 hour)
B
Ms. Winnecuit (5 minutes)
C
Mr. Drudge (30 minutes)
D
Mrs. French (15 minutes)
Explanation
When all calls are equally important, Preston should make the shortest call first so he can finish a task quickly and reduce the total waiting time across the calls. Ms. Winnecuit’s call takes 5 minutes, less than the other calls, so he should call her first.
