Question

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

Answer 1

The equation is y=20x

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.
