Answer:
11.5 hours
Step-by-step explanation:
25 pages every 75 minutes (1 1/4)
Thats means 1 page every 3 minutes (divide 25 and 75 by 25 to get this)
230 pages would mean 690 minutes (times the 3 by 230)
690/6 = 11.5
Answer:
v = 96 km/h
Step-by-step explanation:
Data:

t = 2.5 h
speed = d/t
speed = 240/2.5 = 96 km/h
