Question

UpStudy AI · Accepted Answer

To find out how far Brennan rode in total, we need to add the distances he rode on both trains.

1. **Distance on the first train:** 87.18 miles
2. **Distance on the second train:** 68.9 miles

Now, we will perform the addition:

$$
\text{Total Distance} = 87.18 + 68.9
$$

Let's calculate this step by step:

1. Align the numbers for addition:
   $$
   \begin{array}{r}
   87.18 \
   + 68.90 \
   \hline
   \end{array}
   $$

2. Add the numbers:
   - Start from the rightmost digit (hundredths place): $$8 + 0 = 8$$
   - Next, the tenths place: $$1 + 9 = 10$$ (write down 0 and carry over 1)
   - Next, the units place: $$7 + 8 + 1 = 16$$ (write down 6 and carry over 1)
   - Finally, the tens place: $$8 + 6 + 1 = 15$$

Putting it all together, we get:

$$
\text{Total Distance} = 156.08 \text{ miles}
$$

Thus, Brennan rode a total of $$ \boxed{156.08} $$ miles.
Brennan rode a total of 156.08 miles.
