B. 20 < x < 50
C. 20 > x > 50
D. 20 ≤ x ≤ 50
Answer:
D) 20 ≤ x ≤ 50.
Step-by-step explanation:
Given : , the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.
To find: Write a compound inequality that represents the situation.
Solution : We have given that
Maximum speed = 50 miles per hour.
Minimum speed = 20 miles per hour.
Let x represent the speed .
According to question
maximum speed is 50 or less than 50.
Then we will use less than equal to sing
x ≤ 50
For Minimum speed is 20 or greater than 20 .
x ≥ 20
On combining both statement,
20 ≤ x ≤ 50
Therefore, D) 20 ≤ x ≤ 50.
