I need the options to the questions
The sine function is increasing in the first quadrant.
sin(0) = 0
sin(90) = 1
This means the larger angle will give a larger sine value.
sin(w) > sin(t) -----> w > t
The difference in speed is 41 km /hr.
<h3>What is the difference in speed?</h3>
Average speed is the total distance travelled per time.
Average speed = total distance / total time
The first step is to determine the distance that Mr. Suksod drives.
Distance = average speed x time
82 x (15/60) = 20.50 km
The second step is to determine the average speed of Mr Taylor = 20.50 ÷ (10/60) = 123 km /hr
Difference in speed = 123 - 82 = 41 km /hr

We can use a variable equation to solve this. Let A represent alan's age, B represent bob's age, and C represent Cindy's age. So Bob's age would be Alan's age - 5, or a -5 = B. Then Bob's age would be double Cindy's age, so that means 2 multiplied by Cindy's age = Bob's age, or 2C = B. Your two equations are:
A - 5 = B
2C = B
Also a third equation that helps is A + B + C = 20.
Finally, here are the ages.
Alan = 11 years old
Bob = 6 years old
Cindy = 3 years old.
PS: Sorry, I'm not that good at explaining things, but here are the answers
No it's positive since if you multiply both sides by -1 you will get 5m=20 & m=4
Another method -5m =-20, divide both sides by -5, you will get the same positive m =4
