Answer:
Brady rides at slower speed which is 17 miles/hours for <em><u>3 hours and 36 minutes.</u></em>
Step-by-step explanation:
Given:
Brady rode 70 miles in 4 hours.
For hours he rode at the average rate of 17 miles/hour
For rest of the time he rode at the average rate of 22 miles per hour.
To find the time Braady rode at the slower speed.
Solution:
Total time of riding = 4 hours
Time for which Brady rides at 17 miles/ hour = hours
Distance covered in hours =
So, time for which Brady rides at 22 miles/ hour = hours
Distance covered in hours =
Total distance can be given as:
⇒
Simplifying.
⇒
Total distance given =70 miles.
Thus, the equation to find can be given as:
Subtracting both sides by 88.
Dividing both sides by -5.
∴ hours
Thus, Brady rides at slower speed which is 17 miles/hours for 3 hours and 36 minutes.
Answer:
The inequality is 6x ≥ -24
The solution of this inequality is {x : x ∈ R, x ≥ -4} ⇒ [-4, ∞)
Step-by-step explanation:
- In the inequality not more than means ≤
- In the inequality at least means ≥
Let us solve the question
∵ Six times a number x means 6 × x = 6x
∵ At least means ≥
∴ Six times a number x is at least -24 is 6x ≥ -24
∴ The inequality is 6x ≥ -24
Now we will find the solution of the inequality
∵ 6x ≥ -24
→ Divide both sides by 6
∵ ≥
∴ x ≥ -4
∴ The solution of this inequality is {x : x ∈ R, x ≥ -4} ⇒ [-4, ∞)
