Final answer:
Ms. Vang will approximately take 6 hours to travel from Detroit to Chicago at a speed of 70 miles per hour, covering a distance of 450 miles.
Step-by-step explanation:
The question you've asked involves calculating the time it would take Ms. Vang to travel from Detroit to Chicago at a speed of 70 miles per hour over a distance of 450 miles. To solve this, we use the formula for time, which is Time = Distance / Speed. Plugging in the values we get Time = 450 miles / 70 miles per hour.
To get the time in hours, we perform the division which results in approximately 6.43 hours. However, for estimation purposes and ease of understanding, we can round this to the nearest whole number, providing an estimated time of 6 hours for Ms. Vang to reach Chicago from Detroit, assuming a consistent speed and no traffic delays.
