The time spent for each activity can be found writing an equation based on
the known parameters.
- The duration of the time Stanley spent running is <u>1.5 hours</u>
- The duration of the time Stanley spent swimming is <u>1 hour</u>
- The duration of the time Stanley spent Biking is <u>3 hours</u>
- The distance Stanley cover while biking is <u>48 miles</u>
<u />
Reasons:
The running speed = 9 mph
The biking speed = 16 mph
Swimming speed = 2.5 mph
The time spent running = 0.5 hour + Time spent swimming
Biking time = 2 × Running time
The total distance covered = 64 miles
Required:
Time spent running, swimming, and biking
Solution:
Let <em>t</em> represent the time Stanley spent swimming, we have;
(t + 0.5)·9 + 2.5·t + 2×(t + 0.5)×16 = 64
43.5·t + 20.5 = 64
43.5·t = 64 - 20.5 = 43.5
- The time Stanley spent swimming, t = <u>1 hour</u>
The time Stanley spent running = 0.5 + t
Therefore;
The time spent running = 0.5 hour + 1 hour = 1.5 hour
- Time spent running = <u>1.5 hours</u>
Time spent biking = 2 × Running time
Therefore;
- Time spent biking = 2 × 1.5 hours = <u>3 hours</u>
- The distance Stanley cover while biking, d = 3 × 16 mph = <u>48 miles</u>

Answer:
A. 1
B. slope: 1/2 mile/minute; the slope represents the speed of the car
C. correlation
Step-by-step explanation:
A. The points in the table lie on a straight line, so the correlation coefficient is exactly 1.
__
B. The ratio of distance to time is speed. That ratio for this data is 10 miles/20 minutes = 1/2 mile/minute. This is the slope of the graph.
__
C. Passage of time does not cause the car to go any particular distance, nor does the car's traveling cause time to pass. The best that can be said is that the car's distance traveled is strongly correlated with the time it takes. (The reason the car goes some distance is likely due to a cause not mentioned in the problem statement, for example, it was switched on and the motor started.)
Answer:right
Step-by-step explanation:
Answer:
<em>Bot ratios are equivalent? YES</em>
Step-by-step explanation:
The Semi Scooper Sundae has 10 scoops of ice cream and 6 cherries. The ratio of cherries to scoops of ice cream is:
Simplifying:
Ratio= 3:5
The Super Scooper Sundae has 15 scoops of ice cream and 9 cherries. The ratio of cherries to scoops of ice cream is:
Simplifying:
Ratio= 3:5
Bot ratios are equivalent? YES
80 kilometers is equal to 80,000 meters. This is greater than 1000 meters.
