Simon took a bike trip over the course of a single day. sim rode for the following times:
9: 00 a. m. to 11: 30 a. m. 35 miles

11: 30 a. m. to 11: 45 a. m. 0 miles (rest)

11: 45 a. m. to 2: 15 p. m. 25 miles

-which set of data accurately shows simon's speeds?

a. fastest leg: morning: 16 miles per hour slowest leg: afternoon: 10 miles per hour average speed, all day: 12 miles per hour

b. fastest leg: morning: 14 miles per hour slowest leg: afternoon: 10 miles per hour average speed, all day: 11.4 miles per hour

c. fastest leg: afternoon: 25 miles per hour slowest leg: morning: 17.5 miles per hour average speed, all day: 20 miles per hour

d. fastest leg: afternoon: 17.5 miles per hour slowest leg: morning: 14 miles per hour average speed, all day: 11.4 miles per hour

Option B.

Step-by-step explanation:

Travelling time in the morning 9:00 A.M to 11:30 A.M. = 2.5 hours

Distance traveled by Simon in the morning = 35 miles

Average speed of Simon in the morning = = 14 mph

Travelling time in the afternoon 11:45 A.M to 2:15 P.M. = 2.5 hours

Distance traveled by Simon in the afternoon = 25 miles

Average speed of Simon in the afternoon = = 10 mph

Total time in travelling (2.5 + 2.5 hours and 15 min. rest) = 5.25 hours

total distance covered = 35 + 25 = 60 miles

Average speed for all day =

                                           = 11.4 miles per hour

Therefore, Option B is the correct answer.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
