424/8 =53
(288 - 144)/(6 - 3) = 144/3 = 48
Miguel has a greater rate than Donna by 5 miles per hour.
Answer:
Miguel's rate of change is greater than Donna by 5 mile/hour.
Step-by-step explanation:
Miguel drove for 8 hours at a constant rate.
Total distance covered by him=424 miles.
Rate at which Miguel drove= \(\dfrac{424}{8}\) miles/hour.
=53 miles/hour.
Now, the table for Donna is given as:
Number of hours: 3 6 9
Total miles: 144 288 432
so, the Rate at which Donna drove = \(\dfrac{288-144}{6-3}\)
=\(\dfrac{144}{3}\\ \\=48\) miles/hour
Hence, Miguel has a greater unit rate of change than Donna because the unit rate of change of Miguel is 53 miles/hour while that of Donna is 48 miles/hour.
Hence Miguel's rate is 5 miles/hour more than Donna.
