In 2 seconds an elevator travels 40 feet. In 3 seconds the elevator travels 69 feet in for seconds the elevator travels 80 feet. Write an equation that gives the relationship between the number seconds x and the distance y the elevator travels

The equation is y=20x

Step-by-step explanation:

Speed=distance/time

The distance moved by the elevator is in multiples of 20

Y = 20x

When x = 2 seconds, y=20x=20*2=40feet

When x = 3seonds, y = 20x = 20*3=60feet

When x=4 seconds, y = 20x = 20*4 = 80feet.
