The round trip was 8 miles ( 4 + 4 = 8)
The total time for the trip is 3/10 + 1/2
Rewrite 1/2 as 5/10
Now add 3/10 + 5/10 = 8/10 = 4/5 hour for the 8 mile trip.
Now to find miles per hour, divide total miles by total time:
8 miles / 4/5 hour
When you divide by a fraction flip the fraction over and multiply:
8 x 5/4 = 40/4 = 10
The average rate was 10 miles per hour.
It should be 24 because <span>Pick 3 aces: 4C3 = 4 ways
Pick 2 kings: 4C2 = 6 ways
# of full-house hands: 4*6 = 24</span>
unfortunately I cant manage to understand ur question
