Answer:

9 minutes

Step-by-step explanation:

In terms of hours, the travel times are ...

time = distance/speed

Expected time

te = (30 mi)/(50 mi/h) = 3/5 h = 36 minutes

Actual time

ta = (30 mi)/(40 mi/h) = 3/4 h = 45 minutes

Then the extra time taken is ...

(45 -36) min = 9 minutes

The journey took 9 minutes longer than expected.
