#You may modify the lines of code above, but don't move them!

#When you Submit your code, we'll change these lines to

#assign different values to the variables.

#Let's try something trickier! The variables above represent

#the start time for a run as well as the length of the run

#in minutes. The original values, for example, show a run

#that started at $3$:$48$ and lasted $172$ minutes.

#

#Add some code below that will print the time at which the

#run will end, using normal formatting $($e$.$g$.6$:$40$ for the

#original data above$).$ To do this, you'll need to somehow

#find both the hours and minutes of the new time, convert

#both to strings, and add those to the colon $"$:$"$ to print

#the time.

#

#You may assume that the length of the run will never cross

#$12$:$59($e$.$g$.$ you don't have to worry about going from

#$12$:$59$ to $1$:$00$ or $23$:$59$ to $0$:$00).$ You also don't need to

#worry about the lack of $0$ in front of single$-$digit minute

#counts $($e$.$g$.$ it's fine to show $5$:$07$ as $5$:$7).$

#Add your code here!
