Answer:

50 mi/h

Step-by-step explanation:

Given data

  • Distance traveled 1 (d1): 120 miles
  • Elapsed time 1 (t1): 2.5 hours
  • Distance traveled 2 (d2): 105 miles
  • Elapsed 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
