Step-by-step explanation:

GIVEN: O is the mid point of AC & BD.

Therefore, AO = CO & BO = DO

$\therefore \: AO \: \cong \: CO.. (given) \\ \\ \: \: \: \: \angle \: AOB \: \cong \:\angle \:COD\\..(vertically\:opposite\:angles) \: \\ \\ \& \: \: \: BO \: \cong \: DO.. (given) \\ \\ \therefore \triangle \: AOB \: \cong \: \triangle \:COD \\ ..(by \: SAS \: test \: of \: congruence ) \\ \\ \therefore AB = CD.. \\ (Corresponding \: sides \: of \: congruent \: triangles)$

Two small planes start from the same point and fly in opposite directions. The first plane is flying 25 mph slower than the seco

Talja [164]

Answer:

105 mph = rate of first plane

130 mph = rate of second plane

Step-by-step explanation:

Let r = rate of first plane

then r + 25 = rate of second plane

2r = distance of first plane

2(r + 25) = distance of second plane

2r + 2(r + 25) = 470

2r + 2r + 50 = 470

4r = 420

r = 105 mph

r + 25 = 130 mph
