Question

Suppose p varies inversely as q, and p = 10 when q = 17. What is the approximate value of p when q = 49?

Answer 1

3.47

Explanation:

p varies inversely with q, so:

p = k/q, where k is a constant.

When q = 17, p = 10.

10 = k/17

k = 170

p = 170/q

When q = 49:

p = 170 / 49

p ≈ 3.47
