Abus traveled 120 miles in 2.5 hours. after picking up new passengers, it traveled another 105 miles in 2 hours. what was the average speed of the bus for the entire trip? round to the nearest hundredth, if necessary.48.00 mi/h50.00 mi/h50.25 mi/h52.50 mi/h

50.25mi/h

Step-by-step explanation:

 1. You must calculate the average speed in the first part of the trip with the following formula:

Where is the distance in the first part of the trip and is the time in the first part of the trip.

Then:

2. Now, calculate the average speed in the second part of the trip:

3. The average speed of the bus for the entire trip:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

df =

both have same length
