Question

In a week, an airline operates a flight from San Francisco to New York once a day. The total travel times for this week are:

Sunday: 343 min.
Monday: 314 min.
Tuesday: 401 min.
Wednesday: 341 min.
Thursday: 359 min.
Friday: 407 min.
Saturday: 378 min.

What was the range of flight times for the route that week?

a. 66 min
b. 93 min
c. 29 min
d. 87 min

Answer 1

To find the range of flight times, you need to find the difference between the shortest and longest flight times. The shortest flight time was on Monday at 314 minutes, and the longest flight time was on Friday at 407 minutes. The range is 407 - 314 = 93 minutes. The correct answer is therefore (b) 93 min.
