Question

s is inversely proportional to t
When s = 0.6, t=4
Work out s when t=0.2

Answer 1

0.03

Step-by-step explanation:

S ∝ t, introduce constant, if value of S depends on t only. Let that constant be 'k'.

=> S = kt

When, S = 0.6 & t = 4:

=> 0.6 = k(4)

=> 0.6/4 = k

=> 0.15 = k

Therefore, when t = 0.2

=> S = kt

= (0.15)(0.2)

= 0.03

Answer 2

Step-by-step explanation:

$s \: = kt$

$s = 0.6 \: t = 4$

$put \: this \: value$

$0.6 \div 4 = k \\ 0.15 = k$

$work \: out \: s \: when \: t = 0.2$

$s = 0.15 \times 0.2 \\ s = 0.o3$
