Answer:
D. 423 miles
Step-by-step explanation:
75 miles(3 hours)
66 miles(3 hours)
225+198=423 miles
The greatest possible error of 18.9m is 18.95m - 18.85m = 0.1m
75•15=1125 (this is the area of the bottom rectangle)
10•25=250 (area of the top rectangle)
Now add those together to get the area of the WHOLE shape 250+1125=1375
