Answer:
8 3/4 hours
Step-by-step explanation:
Time is inversely proportional to speed for the same distance. The time for 1.2 times the speed will be 1/1.2 times the given time:
(10.5 h)/1.2 = 8.75 h
It will take 8.75 hours at the increased speed.
10. 4 + 5x < 54
- subtract 4 to the right
- divide both sides by 5
answer: x < 10
11. 2(x + 4) + 3 = 6 - x
- distribute 2 to x and 4
- add 8 and 3
- add -x to left side
- subtract 11 to right side
- divide both sides by 3
answer: x = -5/3
