A.
181 miles
B.

Answer 1

The answer is C. 171. You multiply 30 by 3 to get 90 and then multiply 27 by 3 to get 81. Then you add 81 and 90 to get 171. Hope this helps!

Answer 2

Answer: C

Step-by-step explanation:

• If Tom goes at 30 mph, he will be 90 miles away from the starting point after three hours.
• If Juanita goes at 27 mph, she will be 81 miles away from the starting point after three hours.
• 81 + 90 = 171
• They will be 171 miles apart after three hours.
