Average speed = Distance/ time
Distance = 180 mi
Time = time(final) - time(initial)
To find time will be easier if we translate am and pm into 24 h scale.
am will stay the same, so 10:30 am is 10:30. (initial)
pm will be turned (am time + 12), 3: 00 pm = 3:00 +12 =15:00 (final)
Time = time(final) - time(initial)= 15:00 - 10:30 = 14:60 - 10:30 =4h 30 min
4h + 30 min = 4h + 1/2 h= 4.5 h (time)
Average speed = Distance/ time = 180 mi / 4.5 h = 40 mi/h
Answer is 40 mi/h.
Answer:
1 / 362880
Step-by-step explanation:
There are 9 possible names that could be first.
After that, there are 8 possible names that could be second.
After that, there are 7 possible names that could be third.
So on and so forth.
So the number of permutations is:
9×8×7×6×... = 9! = 362880
The probability of randomly selecting the one order used in the spelling bee is therefore:
P = 1 / 362880
Randy paid $1.38 per candy bar
There are 5 quarters and 3 dimes.
Let's illustrate it as 
Now adding 5 quarters and 5 dimes, we get 
.
5/3 is not equal to 10/8 hence it no longers has the ratio of 5:3 but now has the ratio of 5:4
