Write the ratio as a unit rate
27 miles in 1/2 hour
A:13.5 miles per hour
B:44 miles per hour
C:54 miles per hour
D:56 miles per hour
My answer is B
It’s actually C.54 Miles Per Hour.
To write the ratio of 27 miles in 1/2 hour as a unit rate, we divide 27 by 1/2.
27 ÷ 1/2 = 27 × 2
= 54
Therefore, the unit rate is 54 miles per hour.
The correct answer is C: 54 miles per hour.
To find the unit rate, you need to divide the total miles (27) by the time in hours (1/2).
The ratio 27 miles to 1/2 hour can be expressed as:
27 miles ÷ 1/2 hour
To divide fractions, you can invert the second fraction and multiply:
27 miles × 2/1 hour
Simplifying the expression:
(27 × 2) miles / 1 hour
54 miles / 1 hour
Therefore, the unit rate is 54 miles per hour.
Your answer, B, is correct.
