Answer:

Priya takes 32 minutes and 30 seconds to complete the route and Jibran takes 37 minutes and 30 seconds to complete the route.

Explanation:

We have that Priya (P) and Jibran (J) take 1 h + 10 min working together:


P + J = 60min + 10min = 70 min (1)

Also, Priya can finish the delivery 5 minutes faster than Jibran:


P = J - 5 (2)

By entering equation (2) into (1) we have:


(J - 5) + J = 70 min


2J = 75 min


J = 37.5 min = 37 min + 30 s

Hence, Jibran takes 37 minutes and 30 seconds to complete the route.

Now, by entering J into equation (2):


P = 37 min + 30 s - 5 min = 32 min + 30s

Therefore, Priya takes 32 minutes and 30 seconds to complete the route.

I hope it helps you!
