No it is not 40. Let's see: 12 hrs times 60 minutes= 720 minutes. Divide 720 by 8 to get 90

To find the average time it takes for the bus to cross the city, you need to divide the total time by the number of trips. In this case, you know that the bus crosses the city 8 times in 12 hours.

To convert hours to minutes, you can multiply the number of hours by 60. So, 12 hours x 60 minutes = 720 minutes.

Next, you divide the total time of 720 minutes by the number of trips, which is 8. This gives you the time per trip.

720 minutes รท 8 = 90 minutes.

Therefore, on average, it takes the bus approximately 90 minutes to cross the city.
