Answer:
3.2 miles
Step-by-step explanation:
The number line tells you that the final answer should be between 3 and 4.
To solve this problem you would add up the number of miles Janice ran yesterday and today and subtract this amount from 8.
2.35 + 2.45 = 4.8
Subtract 4.8 from 8.
8 - 4.8 = 3.2
Janet has 3.2 more miles to jog to reach her goal of 8 miles. So yes, the answer should be correct since the number is between 3.0 and 4.0.
