Answer:
Step-by-step explanation:
Let be and
, we plot each curve with the help of graphic tool. In this case, we use Desmos and outcome is presented in the image attached below. Mathematically speaking, a solution to the system of equation exists when
. Graphically speaking, it means that a solution exists when both curves pass through each other.
According to the graphic tool, we conclude that the only solution to the system of equations is .
Answer:
Priya takes 32 minutes and 30 seconds to complete the route and Jibran takes 37 minutes and 30 seconds to complete the route.
Step-by-step explanation:
We have that Priya (P) and Jibran (J) take 1 h + 10 min working together:
(1)
Also, Priya can finish the delivery 5 minutes faster than Jibran:
(2)
By entering equation (2) into (1) we have:
Hence, Jibran takes 37 minutes and 30 seconds to complete the route.
Now, by entering J into equation (2):
Therefore, Priya takes 32 minutes and 30 seconds to complete the route.
I hope it helps you!
