Question

Jacob strode up 12 steps in 6 seconds to reach his apartment on the second floor. How many steps did he climb in 4 seconds? Which is the correct equation that will help us solve the problem? 12: 6 = 4:N 12:6 = N: 4 6:12 =N:4 4:12 = 6: N

Answer 1

Answer:

12 : 6 = N : 4

Step-by-step explanation:

Jacob stride 12 steps in 6 seconds to reach his apartment on the second floor. The number of step he will climb in 4 seconds can be solved below using the following proportion.

It took him 6 seconds to establish 12 steps  .

it will take him 4 seconds to establish N number of steps

cross multiply

12 × 4 = 6N

48 = 6N

divide both sides by 6

N = 48/6

N = 8 steps

Now the correct equation base on the option is as follows:

12 steps is to 6 second which is 12 : 6 will establish an equal proportion with N steps to 4 seconds which is N:4. Therefore,

12 : 6 = N : 4

12/6 = N/4

cross multiply

48 = 6N

N = 48/6 = 8 steps
