The sears tower in chicago is 443 m tall. joe wants to set the world's stair climbing record and runs all the way to the roof of the tower. if joe's average speed is 0.60 m/s, how long will it take joe to climb from street level to the roof of the sears tower?

*this is about average velocity and displacement.

738.3 seconds (12.3 minutes)

If we assume that Joe's speed is 0.6 m/s in the vertical direction, then the total displacement he must cover is 443 meters in the vertical direction. Now, the formula for average speed is:

average speed = total distance / total time
total time = total distance / average speed
total time = 443/0.6
total time = 738.3 seconds

Ibelieve the answer is b. dugout
