Calculation of Distance Covered Each Day

To calculate the distance covered each day by the traveler, we can use the information provided.

According to the given information: - On the first day, the traveler covered 10 km. - On the second day, the traveler covered 30 km more than the previous day.

Let's calculate the distance covered each day:

- First day: 10 km - Second day: 10 km + 30 km = 40 km - Third day: The traveler covered 100 km in total, and we already know the distances covered on the first and second days. Therefore, we can subtract the sum of the distances covered on the first and second days from the total distance to find the distance covered on the third day.

To find the distance covered on the third day, we can use the equation:

Total distance - (Distance covered on the first day + Distance covered on the second day) = Distance covered on the third day

Let's substitute the values:

100 km - (10 km + 40 km) = 50 km

Therefore, the traveler covered 50 km on the third day.
