Question

a particular amusement park ride will make 156 revolutions and 180 seconds at this rate how many revolutions will it make in 2 minutes

Answer 1

Answer:

the particular amusement park ride will make 104 revolutions in 2 minutes

Step-by-step explanation:

First, it is necessary to transform 2 minutes into seconds. We know that 1 minute has 60 seconds, so the number of seconds in 2 minutes is calculated as:

2 minutes * 60 seconds/minute = 120 seconds

Then, we can found the revolutions using a rule of three in which we know that the ride will make 156 revolutions and 180 seconds, then how many revolutions will make in 120 seconds. This is:

156 revolutions -----------------------  180 seconds

         X              -----------------------  120 seconds

Where X is the number of revolution that the ride will make in 2 minutes. Solving for X, we get:

$X = \frac{156*120}{180}$

X = 104 revolutions

Finally, the particular amusement park ride will make 104 revolutions in 2 minutes.

Answer 2

Okay so if it makes 156 revolutions in 180 seconds you can figure out how many revolutions it will make in 2 minutes by first dividing 156 by three. this will tell you how many revolutions it will made in 1 minute (180 seconds divided by 3 = 60) so 156/3=52 you then multiply 52 by two to get the revolutions it will make in two minutes, 52 times 2 = 104 The ride will have made 104 revolutions in 2 minutes.
