Answer:
Step-by-step Solution:
<u>Subtract or add to obtain your answer.</u>
- b + (−1.9) = −3.7
- => b - 1.9 = -3.7
- => b = -3.7 + 1.9
- => b = -1.8
Hence, the value of b is -1.8
Answer:


Step-by-step explanation:
If the rate is x, then the rate of the return is x+25. In both trips, he has 40 miles to travel, therefore, it will take 40/x hours in the first trip and 40/x+25 for the return. As a consecuence

Also,

This means that if he starts at 30 miles per hour, it will take a bit more than 1 hour to be there: 1 hour and 20 minutes in the first trip, and a bit more than 40 minutes (40/55 hours) in the return.
