Question

Preeti walked 3 km in 40 min and Rounak walked 4 km in 50 min.Find the ratio of their walking speed.

Answer 1

Answer:

15:16

Step-by-step explanation:

speed of preeti= 3/40 km/min

speed of rounak= 4/50 km/min

therefore ratio:

$\frac{ \frac{3}{40} }{ \frac{4}{50} }$

which equals to

$\frac{3 \times 50}{4 \times 40}$

i. e. 15:16
