100 miles ............... 2 hours
x miles ................1 hour
x = 100 m / 2 h = 50 m / h
Answer:
7.12 kilometers
Step-by-step explanation:
Add the amounts of kilometers to find the total :
3.8 kilometers + 3.32 kilometers = 7.12 kilometers
Answer:
There is no question stated. If one assume the question is "Does the probability of picking the same color pen change after the first try?," the answer is "No."
Step-by-step explanation:
When the pen is replaced, the probability reverts back to the original value:
There are 7 pens:
5 Blue
2 Red
The probability of picking a red or blue pen on the first try is:
Red = 2/7
Blue = 5/7
When the pen is replaced, the probabilities return to the original values.
Note: This is a perfect application for equations of ratios.
50 40
------- = ------- and so 50x = 1200, or 5x = 120, or x = 24 (miles).
30 x
Answer: 13
