The 3 will complete a lap around the neighborhood in 60 seconds ( 1 minute)
Step-by-step explanation:
The time each of the three can take is 15 , 20, 30 seconds
Now, we want to calculate the time at which all 3 will complete a lap around the neighborhood at the same time

Answer:
Approx. 1343 feet
Step-by-step explanation:
Building A is 71 stories at 875 feet tall. Since the two buildings have the same number of feet per floor, we can divide building A's stories to find the height of 1 story, and then multiply by the stories of building B.
Building A
71 ÷ 71 = 1 story
875 ÷ 71 = 12.32 feet
Each story is approximately 12.32 feet tall
Building B
1 story × 109 = 109 stories
12.32 feet × 109 = 1343.31 feet
Rounded to the nearest foot is 1343 feet.
