Speed is always inversely proportional to time,

i.e., s ∝

t

Answer 2

Question:-

The speeds of three cars are in the ratio 2:3:4. What is the ratio between the times taken by these cars to travel the same distance?

Answer:-

=> Speed is always inversely proportional to time,

i.e., s ∝ 1/t

∴ Ratio of times takes = 1/2:1/3:1/4

=1/2×12 ; 1/3×12 ; 1/4×12

=6:4:3
