Im guessing that by making 10 it will speed up the addition process so it should be
B since (6+4) = 10 then +5 =15

The cars (seats) of a Ferris wheel are positioned 74 feet from its center. If the Ferris wheel makes 4 revolutions every 4 minut

Nataliya [291]

The linear speed of one of the cars is 7.75 feet per second

The cars (seats) of a Ferris wheel are positioned 74 feet from its center.

The radius, r = 74 feet

The Ferris wheel makes 4 revolutions every 4 minutes

Number of revolutions per minute = 1

Angular speed, w = 1 rev/min

Angular speed, w = 0.10472 rad/sec

The relationship between the linear speed (v), and the angular speed (w) is:

v = wr

Substitute w = 0.10472 and r = 74 feet into the formula:

v = 0.10472 x 74

v = 7.75 feet per second

The linear speed of one of the cars is 7.75 feet per second
