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.

50 mi/h

Step-by-step explanation:

Given data

Distance traveled 1 (d1): 120 milesElapsed time 1 (t1): 2.5 hoursDistance traveled 2 (d2): 105 milesElapsed time 2 (t2): 2 hours

The total distance traveled (d) is:

d = d1 + d2 = 120 mi + 105 mi = 225 mi

The total elpased time (t) is:

t = t1 + t2 = 2.5 h + 2 h = 4.5 h

The average speed of the bus for the entire trip (v) is:

v = d/t = 225 mi/4.5 h = 50 mi/h

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
