Step-by-step explanation:

Given

$D = s.t$

Required

Which represents 400km

This question requires options. Since none were given, I will answer on a general term.

Situation 1:

s = 20km/h and t = 20h

$D = s.t$

$D = 20km/h * 20h$

$D = 400km$

Situation 2:

s = 10km/h and t = 40h

$D = s.t$

$D = 10km/h * 40h$

$D = 400km$

Situation 3:

s = 40km/h and t = 10h

$D = s.t$

$D = 40km/h * 10h$

$D = 400km$

So, all you literally have to do is multiply the values of s and t. If the product gives 400, then; that situation is D = 400
