Train a and train b leave the central station at the same time. they travel the same sped, but in opposite directions, with train a heading towards station a, and train b heading towards station b. train a reaches station a after 2 1/2 h. train b reaches station b after 4h. station a and b are 585 mi apart what is the rate of the trains? —— mph

Train B reaches station B after 312 h

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
