The total distance an object travels varies directly with the length of time it travels. if an object travels 32 meters in 18 seconds, how long will it take to travel 80 meters? a. 40 seconds b. 42 seconds c. 45 seconds d. 48 seconds

Step-by-step explanation:

It is given that, the total distance an object travels varies directly with the length of time it travels.

If an object travels 32 meters in 18 seconds so,

.....(1) (k is a constant)

If distance travelled is 80 meters, then the time taken is t say.

.....(2)

On solving equation (1) and (2), we get the value of t as,

t = 45 seconds

Hence, this is the required solution.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
