Answer:
B
Step-by-step explanation:
This is a distance-rate-time problem, so we need to use the equation: , where d is the distance, r is the rate, and t is the time.
Here, we know that the total distance is 150, so d = 150. Also, we are given that Sergio's rate is 60 mph, so r = 60. Put these in:
d = rt
150 = 60t
To solve for t, we divide both sides by 60. Because we are dividing and not multiplying, we know that B is the only one that is incorrect.
Hope this helps!
There are 5+6+4+3+2=20 m&m's in the bag.
Calculate in how many ways you can choose 3 m&m's from 20:
There are 6 yellow m&m's.
Calculate in how many ways you can choose 3 m&m's from 6:
The probability is the number of ways of choosing 3 m&m's from 6 m&m's divided by the number of ways of choosing 3 m&m's from 20 m&m's.
The probability is 1/57.
