Final answer:
The student ran a total distance of 4.15 km over Monday and Tuesday combined, by adding 1.75 km for Monday and 2.4 km for Tuesday.
Step-by-step explanation:
To calculate how far a student ran on Monday and Tuesday, you simply need to add the distances from both days together. On Monday, the student ran 1¾ km, which is equal to 1.75 km when converted to decimal form. On Tuesday, the student ran 2 2/5 km, which is equal to 2.4 km in decimal form. To find the total distance ran over the two days, you would perform the following calculation:
1.75 km (Monday) + 2.4 km (Tuesday) = 4.15 km
Therefore, the student ran a total distance of 4.15 km on Monday and Tuesday combined.
