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.

Step-by-step explanation:
The formula for the surface area of a pyramid is:
B represents the area of the base, which in this case is a triangle. We will figure out the area of the base first, using the formula for the area of a triangle.
A = 10.75
Now we can plug in 10.75 for B.
The cursive L will be the lateral height, which is 5. Since there are 3 sides on the base we can put that in for the number of base sides, and the base is 5.
