Answer:
33.634 ; 134.536 ; d = √[(50t)² + (45t)²]
Step-by-step explanation:
Given the following :
Toyota Prius = East at 50mph
Dodge Circuit = South at 45mph
Distance apart after 30 minutes :
Distance = speed * time
Distance moved by Prius = ( 50mph × 0.5hr) = 25 miles
Distance moved by Circuit = ( 45mph × 0.5hr) = 22.5 miles
Hence Displacement after 30 minutes :
d = √(25² + 22.5²)
d = √625 + 506.25
d = √1131.25
d = 33.634 miles
Distance apart after 2 hours :
Distance = speed * time
Distance moved by Prius = ( 50mph × 2hr) = 100 miles
Distance moved by Circuit = ( 45mph × 2hr) = 90 miles
Hence Displacement after 2 hours :
d = √(100² + 90²)
d = √10000 + 8100
d = √18100
d = 134.536 miles
Distance d in miles after t hours :
d = √[(50t)² + (45t)²]
157.08m is the answer to this question.
Oh sorry to disappoint u i got the answer wrong lol i tried
<span>-5x+2y=9 3x+5y=7
-3x -3x
5y=-3x+7
5 5 5
y=-3/5x + 1.4
so um maybe -1,2
i suck. </span>
Circumference = πD
π*49 = 153.94 (We can leave it as it is because there are two halves to the circle on either side of the training track)
81*2 = 162 (There are two 81 meter lines)
153.94+162 = 315.94m
The length of the training track is 315.94m
Hope this helps! :)
