Answer:
Scale factor of ΔXYZ to ΔUVW will be 1/5
Step-by-step explanation:
Since all the angles of ΔXYZ and ΔUVW are equal, both the triangles will be similar.
ΔXYZ ~ ΔUVW
Since both the triangles are similar, ratio of the corresponding sides will be in the same ratio.
And the scale factor =
=
=
=
Therefore, scale factor of ΔXYZ to ΔUVW will be 1/5
Answer:
Option (G)
Step-by-step explanation:
Let the length of the race = a miles
Since, Speed =
Time taken to cover 'a' miles with the speed = 12 mph,
Time taken '' =
Time taken to cover 'a' miles with the speed = 11 mph,
Time taken '' =
Since the time taken by David to cover 'a' miles was 10 minutes Or hours more than the time he expected.
So,
a = 22 mi
Therefore, distance of the race = 22 mi
Option (G) is the correct option.
