Question

2) s varies directly as t and s = 50 then t = 2. Find the value of s when t = 5.​

Answer 1

Answer:

Given, d varies directly with square of t, which implies d∝t

2

Let the proportionality constant be k, we have d=kt

2

At d=18, then t=3

We get 18=k×9, which implies k=2

Therefore the equation is d=kt

2

At t=5, we get d=50
