Naomi went on a 6.5-mile hike. im the morning, she hiked 1.75 miles, rested, and then hiked 2.4 more miles. she completed the hike in the afternoon. how much farther did she hike in the morning than the afternoon?

First you have to add 2.4 + 1.75 to get the number of miles she hiked in the morning. Then you subtract the the answer of that from 6.5 miles. Then you have to find out the difference of the miles she hiked in the morning and the miles she hiked in the afternoon by subtracting the miles she hiked in the afternoon from the miles she hiked in the morning.

1.75 + 2.4
4.15
6.5 - 4.15
2.35
4.15 - 2.35
1.8 miles is the answer
