Dr. Six drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Six will hit two green lights?

Answers

Answer 1
Answer: Probability 1 * Probability 2 = Probability of both

Let minute = 60 seconds

First light probability = 20/60 (20 seconds out of each 60 seconds)
= 0.33 (recurring)

Second light probability = 35/60 (35 seconds out of each 60 seconds)
= 0.5833 (recurring)

To get a more accurate end probability use the numbers 
20/60 and 35/60 appose to the rounding (on the calculator):

Using the formula at the top:
20/60 * 35/60 = 0.194  (3 DP) 

The probability of that Dr. Six will hit two green lights is 0.194 (3DP)

Mr. Hoya brought 5 watermelons from his grocery store. The watermelons weighed 8 1/4 pound, 9 1/4 pound, 8 7/8 pound, 9 5/8 pound, and 10 3/4 pound. At the party 153 people each ate 1/4 pound serving of watermelon. Was the amount of less than or greater than 8 4/8 or 1/2 pounds? Explain how to solve the problem. Then solve it.

Answers

the amount of watermelon consumed was greater than 8 1/2 pounds.

To determine if the amount of watermelon consumed was less than or greater than 8 1/2 pounds, we need to find the total weight of the watermelons Mr. Hoya brought and then subtract the total amount consumed by the 153 people.

1. Find the total weight of the watermelons:

Total weight = 8 1/4 + 9 1/4 + 8 7/8 + 9 5/8 + 10 3/4

2. Convert all the fractions to a common denominator:

Total weight = (33/4) + (37/4) + (35/4) + (39/4) + (43/4)

3. Add the fractions:

Total weight = (33 + 37 + 35 + 39 + 43) / 4

4. Find the sum:

Total weight = 187 / 4

Now, we'll find the total amount consumed by 153 people:

Total amount consumed = 153 * 1/4

Now, we can compare the total amount consumed to 8 1/2 pounds:

8 1/2 = 17/2 = 34/4

Now, let's compare the values:

Total amount consumed = 153 * 1/4 = 153/4 ≈ 38.25

8 1/2 pounds = 34/4 = 8.5

The total amount consumed (38.25) is greater than 8 1/2 pounds (8.5). Therefore, the amount of watermelon consumed was greater than 8 1/2 pounds.

First add all the watermelon weights together (to add the fourths and the eighths multiply the fourths by 2 (1/4x2=2/8) and add the numerators). Then multiply the number of people (153) by how much they each ate (1/4). Then subtract the total amount eaten (38 1/4) from the total weight (46 3/4) and compare that with 8 1/2... The left overs are actually equal to 8 1/2 pounds :)

The fastest a human has ever run is 27 miles per hour. How many miles per minute did the human run

Answers


(27 mi/hr) x (1 hr / 60 min)  =  (27/60) (mi/min)  =  0.45 mile/minute

Using the same kind of calculation, we can see
that the world record times for other distances
correspond to:

200 meters                  23.31 mph
400 meters                   20.72 mph
800 meters                   17.73 mph
1000 meters                 16.95 mph
1500 meters                 16.29 mph
1 mile (1,609 meters)    16.13 mph
2,000 meters                 15.71 mph
10,000 meters               14.18 mph
30,000 meters               12.89 mph
Marathon  (42,195 meters)    13.10 mph

Except for that one figure at the end, for the marathon,
which I can't explain yet and I'll need to investigate further,
it's pretty obvious that a human being, whether running for
his life or for a gold medal, can't keep up the pace indefinitely.

27 miles per 1 hour
27 miles per 60 minutes
per 1 minute = 27/60 = 9/20 mile
