Answer:
265 miles per 6 hours
Explanation:
Multiply 55 by 1, 2, 3, 4, 5 and so on, to get the speed per each of those hours.
55 x 2 = 110 miles per 2 hours
55 x 6 = 330 miles per 6 hours
55 x 7 = 385 miles per 7 hours
55 x 10 = 550 miles per 10 hours.
Answer choice b (265 miles per 6 hours) is not equivalent to 55mph.
I hope this helps!
