442 mi in 8.5 hr.... now name the units in each rate then write a unit rate.

442 / 8.5 = 52 miles per hour

Yes -- if you're doing long division.

To determine the units in each rate, we'll look at the given information: 442 miles in 8.5 hours.

The units for distance or mileage is miles (mi), and the units for time is hours (hr).

To find the unit rate, we divide the total distance by the total time. In this case, we divide 442 miles by 8.5 hours:

Unit rate = Distance / Time

Unit rate = 442 miles / 8.5 hours

Simplifying the calculation, the unit rate is approximately 52 miles per hour (mi/hr).

So, the units in each rate are: miles (mi) for distance and hours (hr) for time. The unit rate is 52 miles per hour (mi/hr).
