Given:
Jada traveled 135 miles in 3 hours.
Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.
To find:
How far did Jada travel in 1 hour?
Solution:
We have,
Distance traveled by Jada in 3 hours = 135 miles
Then,
Distance traveled by Jada in 1 hour = miles
= 45 miles
Therefore, Jada travel 45 miles in 1 hour.
Answer:
Step-by-step explanation:
Circle A has center (-2, 3)
Circle B has center (2, -2)
Circle A can be mapped to Circle A' by a translation:
Center Rule of translation New center
(x, y) (x+4, y-5)
A(-2, 3) A'(-2+4, 3-5) A'(2, -2)
Circle A with radius r 1=2
Circle B with radius r 2=3
Scale factor= r 2/r 1 = 3/2 = 1.5
Since any two circles can be translated to have the same center, the dilation r2/r1 proves the circles are similar where r1 and r2 are the radii of the circles.
The Circle A' and circle B both have center (2, -2). Then circle A' can be mapped to circle B by a dilation with center (2, -2) and a scale factor 3/2=1.5. So circle A and circle B are similar.
Therefore: Translation right 4, down 5, and then a dilation of 1.5 is true.
Translation down 5, right 4, and then a dilation of 1.5 is true.
