Answer :
Indigrid dug a trench totaling 27/20 meters after two days. A good estimate for the total length is approximately 1.5 meters when rounding for a simpler figure.
The student asked about the total length of a trench that Indigrid dug over two days. On the first day, Indigrid dug a trench 18/20 meters long, and on the second day, she dug an additional 9/20 of a meter.
To find the total length, we add these two quantities together:
First Day: 18/20 meter
Second Day: 9/20 meter
Total Length = 18/20 meter + 9/20 meter
= 27/20 meters
To give a reasonable estimate, we might want to convert this to a mixed number for easier understanding. 27/20 is the same as 1 meter and 7/20 meter. Since 7/20 is close to half a meter, a reasonable estimate could be around 1.5 meters in total.
