Plane b is flying 55mph faster than plane a and can fly 4275 miles in the same amount of time it takes plane a to fly 4000 miles. find the amount of time it takes for each plane to travel their respective distances.

it takes 5s for each plane to travel their respective distances

Step-by-step explanation:

Let a = speed of plane A

Let b = speed of plane B

b = 55 + a

Time for plane A to fly 4000 miles

= 4000/a

Time for plane B to fly 4275 miles

= 4275/b

Since it takes same amount of time

4000/a = 4275/b

4000b = 4275a1

Put b = 55+a in eqn

4000(55+a) = 4275a

220000+4000a = 4275a

275a = 220000

a = 800

b = 55 +800 = 855

Time for plane A to fly 4000 miles

= 4000/800 = 5s

Time for plane B to fly 4275 miles

= 4275/855= 5s

i can you with this question sweetie!
