Question

Which of the following represents the lowest speed in miles per hour?

6 miles in 1/8 hour
11 miles in 1/4 hour
16 miles in 3/8 hour
20 miles in 1/2 hour​

Answer 1

6 miles in 1/8 of an hour is travelling at 48mph (6x8)
11 miles in 1/4 of an hour is travelling at 44 mph ( 11x4)
16 miles in 3/8 of an hour is travelling at 42.4 mph (16/3 = 5.3, 5.3 x 8)
20 miles in 1/2 an hour is travelling at 40mph (20x2)

Answer 2

20 miles in 1/2. That would be 40 miles per hour

Explanation:

6 ÷ 1/8 is the same at 6 x 8 = 48

11 ÷1/4 is the same as 11 x 4 = 44

16 x 3/8 is the same as 16 x 8/3 = 42 2/3

20 ÷ 1/2 is the same as 20 x 3 = 40
