A cheetah’s distance traveled varies directly with the amount of time it runs. The cheetah travels 90 m in 2.5 s.? How many meters will it travel in 4 s?

Answer 1

Kennedy Adams

#=144# m

This can be done by finding the constant or just write as a direct proportion equation and cross- multiply.

The cheetah will run further in 4 sec than in 2.5 sec.

#x/4 = 90/2.5#

#x = (4 xx 90)/2.5#

#=144# m

Since the cheetah's distance traveled varies directly with the amount of time it runs, we can use the formula for direct variation, (d = kt), where (d) is the distance traveled, (t) is the time, and (k) is the constant of variation.

Given that the cheetah travels 90 meters in 2.5 seconds, we can find (k) by rearranging the formula to (k = \frac{d}{t}): [k = \frac{90}{2.5} = 36]

Now that we know (k), we can find out how many meters the cheetah will travel in 4 seconds using the formula (d = kt): [d = 36 \times 4 = 144]

The cheetah will travel 144 meters in 4 seconds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
