Question

Two planes are 2725 miles apart and are traveling toward each other one plane is traveling 110 mph faster than the other plane The plains pass each other in 2.5 hours find the speed of each plane

Answer 1

Answer:

therefore x  = 600 mph

therefore the speed of the other plane  y = x - 110 = 600 - 110 = 490 mph

Step-by-step explanation:

i) Two planes are 2725 miles apart and are travelling towards each other.

ii) One plane is travelling 110 mph faster than the other plane.

iii) the planes pass each other in 2.5 hours

iv) let the speed of one plane be x mph

v) let the speed of another plane be y mph

vi) therefore x  - y = 110 mph

vii) and also x + y = 2725/2.5 = 1090

viii) adding the equation in vi) to the equation in vii) we get 2x  = 1200

    therefore x  = 600 mph

ix) therefore the speed of the other plane  y = x - 110 = 600 - 110 = 490 mph
