Answer 4

She ran her bike 10 miles 2 time. So she was riding her bike for 20 miles. And you just add 2 to 20 because she swam an additional 2 miles.

Answer 5

Oops wrong.
She rode her bike for 10 miles.
Ran 20 miles(10*2)
and swam 2 miles.

Answer 6

So it's D. Multiply 10 × 2. Then add 10 and 2 to the product.
Multiply 10 × 2 represents how long she ran.
Adding 10 represents how much she rode her bike.
Adding 2 represents the miles she swam.
