Answer:
To calculate the time it takes for Dora to travel 7 miles at a speed of 70 miles per hour, we can use the formula:
Time = Distance / Speed
Plugging in the values, we have:
Time = 7 miles / 70 miles per hour
Simplifying the equation, we get:
Time = 0.1 hours
Therefore, it takes Dora 0.1 hours (or 6 minutes) to travel 7 miles at a speed of 70 miles per hour.
