Answer:

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.

Answer:

  (Marlins, 6.76×10^5), (Pirates, 9.68×10^5), (Angels, 1.87×10^6), (Cardinals, 1.98×10^6)

  most: Cardinals

Step-by-step explanation:

First, you compare exponents. Higher positive powers are larger. 10^5 < 10^6.

If the exponents are the same, you compare the mantissas. These are compared in the usual way. 6.76 < 9.68, and 1.87 < 1.98.

Of course, the team with the greatest attendance is the one that is last on the least-to-greatest list.
