Question

The fastest sprinter in the world can run at a speed of about 36 km/hr while a cat can run at a speed of 48 km/hr. How many seconds would a cat take to run the distance which the sprinter runs in 30 seconds?

Answer 1

Answer:

22.5 seconds.

Step-by-step explanation:

The fastest sprinter in the world can run at a speed of about 36 km/hr i.e. 600 meters per minute, while a cat can run at a speed of 48 km/hr i.e. 800 meters per minute.

Now, the sprinter runs in 30 seconds i.e. 0.5 minutes the distance (600 × 0.5) = 300 meters.

Now, the cat will take to run a distance of 300 meters, $\frac{300}{800} = 0.375$ minutes i.e. 22.5 seconds. (Answer)
