Answer:
-17
Step-by-step explanation:
4) 1 mi/6min * 60 min/1h = 1/10 mi/h = 0.1 mi/h
5) 175 mi *1 h/50 mi = 3.5 h
6) Mr. Smith - 9 min -from school to the park.
Mr. McNeil walks twice as fast, that means if s is a speed of Mr. Smith,
then 2s is a speed of Mr. McNeil.
Distance from school to the park = 9*s, distance from school to the park and back = 2*9*s.
Time= Distance/Speed
For Mr. McNeil:
Time from school to the park and back= distance from school to the park and back/ speed of Mr. McNeil = 2*9*s/2s = 9 min.
Answer:2/3
Step-by-step explanation:There are 52 cards in a standard deck: 13 ordinal cards (Ace - 10, Jack, Queen, King) and 4 of them - one to each suit (hearts, diamonds, clubs, spades) and so we have
4
×
13
=
52
.
There are 8 cards that fit the question (4 each of aces and kings).
And so in a random draw, the odds of drawing one of those 8 cards out of the total number of 52 is:8/52
which we can simplify:
8/52=2/13
The answer will be 3/12 because you multiplay across so 3/4 x 1/3 so 3x1=3 and then 4x3=12
