For this case what you can do is an average to calculate the number of hours it will take them to work together:
Let
t: average time.
hi: hours worked for each one.
n: number of teams.
The average will be given by:
t = (h1 + h2) / (n)
Substituting both values:
t = ((15) + (10)) / (2) = 12.5
answer
it would take 12.5 h to pave that same section of highway if both crews worked together
