Final answer:
The problem involves converting kilometers into meters. Since 1 km equals 1000 meters, we find that Tessa ran 13000 meters per day. Multiplying by 3 days, we find she ran a total of 39000 meters.
Step-by-step explanation:
The problem is asking to find out how many meters Tessa ran in three days, given that she runs 13 kilometers per day. We first need to understand that 1 kilometer (km) equals 1000 meters (m). Therefore, we will need to convert kilometers into meters.
Let's calculate:
The amount Tessa runs per day is 13 km. Knowing the conversion factor of 1 km = 1000 m, we simply multiply the given kilometers by 1000 to convert it into meters.
13 km/day * 1000 m/km = 13000 m/day.
So, Tessa runs 13000 meters in a day.
For 3 days, we have to multiply this by 3:
13000 m/day * 3 days = 39000 meters in total.
So, Tessa ran 39000 meters in all in these 3 days.
