C-11-Q073mediumsingle_mcq

Two persons $A$ and $B$ traverse a fixed distance in $t_1$ and $t_2$ minutes respectively. The ratio $v_1 : v_2$ of their average velocities is—

a $t_1 : t_2$
b $t_2 : t_1$
c $t_1 + t_2 : 1$
d $1 : t_1 t_2$

ব্যাখ্যা

For a fixed distance, speed is inversely proportional to time, so $v_1:v_2=\dfrac{1}{t_1}:\dfrac{1}{t_2}=t_2:t_1$ . The person taking less time is faster, confirming the inverse ratio.
