1:</h2>
- A mile unit is equal to 1760 yards. inches =mile * 63360 2*63360=126720
2 Miles = 126720 Inches
- There are 36 inches in a yard
3600/36= 100
3600 inches = 100 yards
6800/1000 = 6.8
6800 m = 6.8 km
15000/100=150
15000 cm=150 m
2:
a) Johnson ran yard in second= 9
1 minute = 60 second
Johnson ran yard in one minute= 9 *60= 540 yards
b) Johnson ran yard in second= 9
1 hour = 60 minutes *60 second= 1200 seconds
Johnson ran yard in one hour= 9 *1200= 10,800 yards
c) Johnson ran yard in one hour= 9 *1200= 10,800 yards
1 mile = 1760 yards
miles did he run in one hour= 10,800 / 1760 =6
Johnson ran 6 mile in one hour
Answer:
RC = 40
Step-by-step explanation:
Note that the circumcentre is equally distant from the triangle's 3 vertices.
That is : PC = RC = QC
Equate any pair and solve for x
Using RC = PC, then
5x - 15 = 3x + 7 ( subtract 3x from both sides )
2x - 15 = 7 ( add 15 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Hence
RC = (5 × 11) - 15 = 55 - 15 = 40 units
Answer: 
Step-by-step explanation:
Given: Distance traveled by Smith = 
mile.
Time taken = 
hour
Unit rate in miles per hour = ( Distance traveled by Smith) ÷ (Time taken)
Unit rate =
