To find out how far you drove in 1 hour, you can calculate the average speed by dividing the total distance by the total time.

Formula:

$\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}$

Substituting the given values:

$\text{Average Speed} = \frac{210.5 \, \text{miles}}{2.5 \, \text{hours}}$

Calculation:

$\text{Average Speed} = 84.2 \, \text{miles per hour}$

Thus, you drove 84.2 miles in 1 hour.

1. How would the calculation change if the time was given in minutes instead of hours?
2. What would the distance be for a 30-minute drive at this speed?
3. How long would it take to drive 420 miles at the same speed?
4. What is the formula for converting miles per hour to kilometers per hour?
5. How can you calculate the fuel efficiency for this trip if given the total fuel used?

Tip: When solving rate problems, always ensure that the units for distance and time are consistent.
