Answer:
Distance between Montpelier and Columbia is 1020
Step-by-step explanation:
51 mi/hr average:
d = 51 t
60 mi/hr average:
d t = 60*(t-3)
Substitute (1) into (2)
51 t = 60*(t-3)
51 t = 60 t + 180
9 t = 180
t = 20
d = 51 t
= 51 (20)
= 1020
let see distance is 1020 lets check
51 t = 60 * (t-3)
51 (20)= 60* (20-3)
1020 = 60*17
1020 = 1020
Answer:
The difference of <u>12,583 feet</u> in elevation between the mountain and the valley.
Step-by-step explanation:
Given:
A mountain is 12,408 feet above sea level, and a valley is 175 feet below sea level.
Now, to get the difference in elevation between the mountain and the valley.
As mountain is above sea level = 12,408 feet.
And valley is below sea level = 175 feet.
So, by adding we get the difference in elevation between the mountain and the valley:


Therefore, the difference of 12,583 feet in elevation between the mountain and the valley.
6 friends share 5 meat pies...
each friend eats half a pie.....6 * 1/2 = 6/2 = 3 pies eaten
so now there r 2 pies left
2/6 = 1/3.....so each friend has to eat 1/3 of a pie
X/3+7
co-efficient=1/3
how?
x/3 is also the same as x(1/3).
