Answer:
The strategies (2), (3) and (5) can be applied.
Step-by-step explanation:
In this case we need to compute the product of 629 × 100.
The product can be found in the following ways:
- multiplying (600 + 20 + 9) x 100

- putting 2 zeros on the end of 629

- multiplying (6,000 + 200 +90) x 10

Thus, the strategies (2), (3) and (5) can be applied.
Part A: 1 kilometer = 1000 meters
20 kilometers = 20 * 1000
= 20000m
Part B: 5 kilometer = 3.1 miles
20 kilometer = 4 * 3.1
= 12.4 miles
