<h2>
Average speed of biking is greater than average speed for the entire race.</h2>
Step-by-step explanation:
Total distance Julie traveled in triathlon = 22.2 miles
Total time taken = 2.15 hours.
We have
Total distance = Average speed x Time taken
22.2 = Average speed x 2.15
Average speed = 10.33 miles per hour.
We also have the function m = 13.8h represents the miles m Julie biked in h hours. This is also similar to
Total distance = Average speed x Time taken
m = 13.8 h
Average speed of biking = 13.8 miles per hour.
Average speed of biking > Average speed for the entire race
Average speed of biking is greater than average speed for the entire race.
Answer:
Step-by-step explanation:
<u>Given</u>
- Capacity of a boat = 1000 pounds
- Equipment = 300 pounds
- Boxes = 25 pounds each
- Number of boxes = x
<u>Required inequality</u>
- 300 + 25x ≤ 1000
- 25x ≤ 700
- x ≤ 700/25
- x ≤ 28 boxes
Let
x = number of minutes of local calls.
y = number of minutes of international calls.
By writing the system of equations we have:
0.06x + 0.15y = 69.84
x + y = 852
Solving the system
Clear y from equation two
y = 852-x
Replace y in equation 1
0.06x + 0.15 (852-x) = 69.84
Clear x
0.06x + 127.8 - 0.15x = 69.84
127.8 - 69.84 = 0.15x -0.06x
57.96 = 0.09x
x = 57.96 / 0.09 = 644
x = 644
Replace x in any of the two equations and clear y:
x + y = 852
y = 852-644
y = 208
answer
number of minutes of local calls = 644
number of minutes of international calls = 208
Answer:
5(9+x)
Step-by-step explanation:
5 x 9 = 45
then if do 5 times x it would look like 5x
