1 answer:
Answer:
Please find the attached traced distance time graph
Step-by-step explanation:
The given parameters are;
The time at the start of Don's journey = 2 pm.
The distance Don drives one hour after leaving home = 45 miles
The speed (Distance/time) Don drove during that time = 45/1 = 45 mph
The time at which Don first stop driving = 2 pm + 1 hour = 3 pm
Don then stops for 90 minutes
The time after the duration at which Don stops driving = 3 pm + 90 minutes = 3 pm + 1.5 hours = 4.30 pm
At 4.30 pm. Don then starts driving home at 15 mph
The distance from Don's home from where Don stopped is 45 miles, therefore;
Time (Distance/speed) for Don to get home = 45 miles/15 mph = 3 hours
Time Don arrived home = 4.30 pm + 3 hour = 7.30 pm.

Answer:
40,320.
Step-by-step explanation:
We are asked to find the number of ways in which 8 books could be arranged on a shelf.
The 1st could be arranged in 8 ways. Since one place is filled, so 2nd book could be arranged in 7 ways.
Similarly, the 3rd book could be arranged in 6 ways as first two places are already taken. This process will go on.
So the 8 books can be arranged in
Therefore, 8 books could be arranged in 40,320 ways.
