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.

u what ?

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
