Problem 1:

A bus travelled 70 miles in two hours. How many miles did the bus travel each hour?

#### Solution:
To find out how many miles the bus traveled each hour, we need to divide the total distance by the total time.

- Total distance = 70 miles
- Total time = 2 hours

The formula is:
\[
\text{Miles per hour} = \frac{\text{Total distance}}{\text{Total time}}
\]

Substitute the values:
\[
\text{Miles per hour} = \frac{70}{2} = 35
\]

So, the bus traveled 35 miles each hour.

#### Final Answer:
\[
\boxed{35}
\]

Problem 2:

A school has 120 students. How many students are needed in each row to make 12 rows with equal students in each row?

#### Solution:
To find out how many students are needed in each row, we need to divide the total number of students by the number of rows.

- Total students = 120
- Number of rows = 12

The formula is:
\[
\text{Students per row} = \frac{\text{Total students}}{\text{Number of rows}}
\]

Substitute the values:
\[
\text{Students per row} = \frac{120}{12} = 10
\]

So, there are 10 students in each row.

#### Final Answer:
\[
\boxed{10}
\]

Problem 3:

There are 7 chocolates in each jar and there are 5 jars. How many chocolates are there in total?

#### Solution:
To find the total number of chocolates, we need to multiply the number of chocolates in each jar by the number of jars.

- Chocolates per jar = 7
- Number of jars = 5

The formula is:
\[
\text{Total chocolates} = \text{Chocolates per jar} \times \text{Number of jars}
\]

Substitute the values:
\[
\text{Total chocolates} = 7 \times 5 = 35
\]

So, there are 35 chocolates in total.

#### Final Answer:
\[
\boxed{35}
\]
