Answer 1

Answer:

13 levels

Step-by-step explanation:

Direct variation can be expressed using the formula:

y = kx, where 'k' is the constant of variation

Since Michael can move up 5 levels in 55 minutes:

n = km, where 'n' is the number of levels and 'm' is the number of minutes:

5 = 55k

k = 1/11

To find the number of levels after 143 minutes:

n = (1/11)(143)

n = 13 levels
