If two cars cover the same distance in $5$ and $4$ minutes, the ratio of their speeds is—

a $5:4$
b $4:5$
c $1:1$
d $9:20$

ব্যাখ্যা

Speed is inversely proportional to time for equal distances, so the speed ratio is the reciprocal of the time ratio: $\dfrac{1}{5}:\dfrac{1}{4}=4:5$ . The car taking $4$ minutes is the faster one.
