Answer:

a. 100 mph

b. 500 mph

Step-by-step explanation:

a.

Let the speed of Lindbergh's plane be x.

Today's planes are 5 times faster, so their speed is 5x.

Today's planes speed is 400 mph faster than Lindbergh's speed.

x + 400 = 5x

5x = x + 400

4x = 400

x = 100

Lindbergh's speed was 100 mph

b. 5x = 5 * 100 = 500

Today's planes fly at 500 mph
