Final answer:
Driving at 70 miles per hour for 3 hours will cover a distance of 210 miles, making option b) the correct answer.
Step-by-step explanation:
To determine how far you will travel in 3 hours when driving at a constant speed, you can use the formula for distance:
Distance = Speed × Time
Given that the speed is 70 miles per hour, and the time is 3 hours, you can calculate the distance as follows:
- Multiply the speed (70 mph) by the time (3 hours).
- The calculation will therefore be 70 mph × 3 hours = 210 miles.
Therefore, the correct answer is b) 210 miles.
It is important to compare this reasonable answer against typical travel scenarios to ensure its accuracy. For instance, if traveling 70 miles in one hour, it is expected to travel 210 miles in three hours, which aligns with our calculation.
