100 miles in 4 hours. The unit rate would be 25 miles per hour.
100miles / 4hrs = 25 miles per hour
Therefore, for every hour you travel, you will gain 25 miles. Or for every 25 miles you travel, you've spent 1 hour traveling it.
y = 25x
where y is the total miles traveled, 25 is the constant unit rate, and x is the number of hours traveled.
for example: you traveled for 8 hours and you want to know how long you've traveled while maintaining the rate of 25mph. Just use the formula
y = 25x
y = 25(8)
y = 200 miles. you have traveled 200 miles in 8 hours.
Answer:
= 105
Step-by-step explanation:
Answer:
The answer to your question is 75 cm
Step-by-step explanation:
Data
Student calculator Demonstration calculator
width = 15 mm width = 4.5 cm
height = 250 mm height = ?
Process
1.- Convert the width of the demonstration calculator to mm
10 mm ---------------- 1 cm
x ---------------- 4.5 cm
x = (4.5 x 10) / 1
x = 45 mm
2.- Use proportions to find the height of the demonstration calculator
250 / 15 = x / 45
- Solve for x
x = (250 x 45) / 15
-Simplification
x = 11250 / 15
-Result
x = 750 mm
3.- Conclusion
The height of the demonstration calculator is 750 mm or 75 cm
