We want to find how far Pasha will have traveled after 4 hours if she travels at a constant speed. To do so, we will find the unit rate, which is her speed, and multiply it by 4 hours. We know that Pasha had traveled 217 miles in 3.5 hours. Let's write a rate to show this situation.
217 mi/3.5h
A unit rate is a rate that has been reduced to a denominator of 1 unit. In this case, the unit rate is the number of miles per hour traveled by Pasha, which is her speed. Let's find the unit rate! For simplicity, we will ignore the units.
We found the unit rate!
217 mi/3.5h = 62 mi/1h
As we can see, Pasha travels at a speed of 62 miles per hour. Now we can multiply the unit rate by 4 hours.
62 mi/1 h * 4 h = 62 mi * 4 = 248 mi
Pasha will have traveled 248 miles after 4 hours.
