Laura is walking quickly and finds that she travels 54 feet in a span of 12 seconds. Which of the following is the speed at which Laura is walking? (1) 4.5 feet per second (2) 4.75 feet per second
(3) 5.25 feet per second
(4) 5.5 feet per second

(1) 4.5 feet per second

Step-by-step explanation:

Given;

distance traveled by Laura, d = 54 feet

time to taken for Laura  to cover this distance, t = 12 seconds

Laura's speed is given by the following equation;

speed = distance / time

Laura's speed = 54 ft / 12 s

Laura's speed =  4.5 feet per second

Therefore, the speed with which Laura is walking is 4.5 feet per second.

a - base

b - exponent
