Answer:
209 inches
Step-by-step explanation:
95% of 220 is 209 inches so therefor it would be 209 inches.
The length of hours Gilbert drove is 7.5 hours.
The length of hours Brian drove is 4.1 hours.
<u>Step-by-step explanation</u>:
- Gilbert averaged = 45 miles per hour
- Brain averaged = 65 miles per hour
- Total hours = 11.6 hours
- Total distance = 604 miles
Let 'x' be the hours Gilbert drove.
Let 'y' be the hours Brian drove.
x+y = 11.6 -----(1)
45x+65y = 604 -----(2)
Multiply (1) by 45 and subtract (2) from (1)
45x+45y = 522
-(<u>45x+65y = 604</u>)
<u> -20y = -82 </u>
y = 82/20
y = 4.1 hours
The length of hours Brian drove = 4.1 hours
Substitute y=4.1 in (1)
x+4.1 = 11.6
x = 7.5 hours
The length of hours Gilbert drove = 7.5 hours
The perimeter is 86 m.
When you add the 18 with the 11, you get the length of the bottom side, which is 29. When you add the nine and the 6, you get the length of the left side, which is 15. Now add everything together.
18 + 6 + 11 + 9 + 29 + 15 = 86 m
Hope I helped. Good luck!! : )
