1. The problem states that a helicopter is flying at a velocity of 10.0 meters per second to the west and we need to find how far it will fly in 70.9 seconds. 2. The distance traveled by an object moving at a constant velocity can be found using the formula: $$distance = velocity \times time$$ 3. Substitute the given values: $$distance = 10.0 \times 70.9$$ 4. Calculate the product: $$distance = 709$$ 5. The distance is 709 meters. Final answer: 709 meters.
