Question

A cheetah can cover 50 yards in 5⁄2 seconds. How long will it take a cheetah at the same speed run 80 yards?

Answer 1

It will take the cheetah 4 seconds to run 80 yards.

Step-by-step explanation:

Given,

Distance covered by Cheetah in 5/2 seconds = 50 yards

Ratio of distance to time = $50:\frac{5}{2}$

Let,

x be the time required to cover 80 yards.

Ratio of distance to time = 80 : x

Using proportion;

Ratio of distance to time :: Ratio of distance to time

$50:\frac{5}{2}::80:x$

Product of extreme = Product of mean

$50*x=\frac{5}{2}*80\\50x=\frac{400}{2}\\50x=200$

Dividing both sides by 50

$\frac{50x}{50}=\frac{200}{50}\\x=4$

It will take the cheetah 4 seconds to run 80 yards.
