Question

last year, andrea ran about 120 kilometers during the months of march, april, and may. estimate how many more kilometers she ran during those three months than she ran this year. round to the nearest 1 kilometer. total distance andrea ran (kilometers) march: 48.7 april: 31.2 may: 35.66 andrea ran about km. this is about km less than last year.

Explanation:

Step1: Calculate the total distance Andrea ran this year

Add the distances for March, April, and May.
$$48.7 + 31.2+35.66=115.56$$

Step2: Find the difference between last year's and this year's distance

Subtract this year's total from last year's (120 km).
$$120 - 115.56 = 4.44$$

Step3: Round the result

Round 4.44 to the nearest 1 kilometer. Since \(4.44<4.5\), it rounds to 4.

Answer:

Andrea ran about \(116\) km (after rounding \(115.56\) to the nearest whole number). This is about \(4\) km less than last year.
