Answer :
Final answer:
The total length of the trench Eli dug is the sum of two fractions, 18/20 and 17/20, which equals 35/20 meters. None of the provided options match this total, but the closest reasonable estimate given is 35/20 meters.
Explanation:
The student is asking about finding the total length of a trench by adding two fractions together. Eli dug a trench 18/20 of a meter long on the first day and 17/20 of a meter long on the second day. To find the total length, we simply add these two fractions together:
18/20 + 17/20 = (18 + 17)/20 = 35/20 meters.
After simplifying, we see that 35/20 is the same as 1 and 15/20, or 1 and 3/4 meters when further simplified. Therefore, the closest reasonable estimate from the given options is 35/20 meters. It's important to note that the other provided options are not equivalent to 35/20 meters.
