The time difference is 55 minutes

Step-by-step explanation:

If it takes 1 hour & 50 minutes (1.83 hours) to make the drive at 105 km/h, the total distance between San Diego & LA is 192.15 km.

At the speed of 70 km/h, it would take you 2.745 hours to complete the drive for that same distance.

This is equivalent to 2 hours and 45 minutes.

Finally, the difference between one and the other is 55 minutes.
