Final answer:
Mrs. Holt walked 500 meters to the market, calculated by converting her speed of 3 km/h to meters per second and then multiplying by the time she walked in seconds.
Step-by-step explanation:
The question is asking how many meters Mrs. Holt walked if she took 10 minutes to go to the market at an average speed of 3 km/h. To find this, we first need to convert the average speed from km/h to meters per second. The conversion is done in two steps:
- Convert kilometers to meters: 1 km = 1000 meters.
- Convert hours to seconds: 1 hour = 3600 seconds.
So the calculation for converting 3 km/h to m/s is:
3 km/h * (1000 meters/1 km) * (1 hour/3600 seconds) = 0.8333 meters/second.
Now, since Mrs. Holt walked for 10 minutes, we convert that time to seconds:
10 minutes * 60 seconds/minute = 600 seconds.
Finally, we can calculate the distance she walked by multiplying her speed by time:
0.8333 meters/second * 600 seconds = 500 meters.
Therefore, Mrs. Holt walked 500 meters to the market.
To check if the answer is reasonable, consider that traveling at 3 km/h for a full hour would cover 3 kilometers, which is 3000 meters. So, for 10 minutes, which is one-sixth of an hour, one-sixth of 3000 meters is indeed 500 meters, making the answer reasonable.
