Answer:
Eudora ran for 30 minutes and use the jetpack for 1 hour and 30 minutes
Step-by-step explanation:
Lets call x the time she ran and y the time she was using a jetpack (in hours), we have
12x + 76y = 120
Since it took 2 hours we have that x+y = 2, hence y = 2-x. We can replace y in the equation above, obtaining
12x + 76(2-x) = 120
12x+ 152 - 76x = 120
12x-76x = 120-152
-64x = -32
x = -32/-64 = 1/2 (30 minutes)
As a result
y = 1-1/2 = 3/2 (1 hour, 30 minutes)
She ran for 30 minutes and use the jetpack for 1 hour and 30 minutes.
. Distance = Speed * Time
Let s represent the speed of the cars in miles per hour. The problem statement tells you
.. red car distance + 25 miles = blue car distance
.. s*3 + 25 = s*(3 + 0.5)
.. 25 = 0.5s ... subtract 3s from both sides
.. 50 = s ... multiply by 2
The speed of the red and blue cars is 50 miles per hour.
The angle sum of quadrilateral is 360 so just 360 - 120- 48 - 92 so the fourth angle should be 100°
the area of triangle is base X height /2 so the answer is 6 x 8 /2 = 24
