Question

Maria walks 16 meters every 10 seconds how far does she walk in 45 seconds?

Answer 1

Maria walks at a rate of 16 meters every 10 seconds, which translates to 1.6 meters per second. To find out how far she walks in 45 seconds, we multiply her walking rate by 45, resulting in a distance of 72 meters.

Step-by-step explanation:

The question asks us to determine the distance Maria walks in 45 seconds, given her walking rate of 16 meters every 10 seconds. To find the distance Maria walks in 45 seconds, we can set up a proportion. Since she walks 16 meters in 10 seconds, we can express her walking rate as 1.6 meters per second.

Step 1: Calculate Maria's walking rate per second which is 16 meters / 10 seconds = 1.6 meters per second.

Step 2: Multiply Maria's walking rate per second by the total time she walks, which is 45 seconds. This step can be summarized by the equation:
Distance = Rate × Time

Therefore, Maria's distance walked in 45 seconds = 1.6 meters/second × 45 seconds = 72 meters.

Answer 2

72 m

Step-by-step explanation:

The unit rate is

16 m

----------- = 1.6 m/sec

10 sec

and so, in 45 sec, Maria walks:

(1.6 m/sec)(45 sec) = 72 m
