Answer :
It will take Joe 738.3 seconds (12.3 minutes) to climb from street level to the roof of the sears tower.
What is speed?
- The definition of speed is the rate at which an object's position changes in any direction.
- Speed is defined as the ratio of distance traveled to time spent traveling.
- Because it has only one direction and no magnitude, speed is a scalar quantity.
- Speed is a measure of how quickly something moves or is done, or how fast something moves.
- A car traveling at 45 miles per hour is an example of speed.
- Someone cleaning a room in 10 minutes is an example of speed.
- A jaguar's speed is an example of speed.
To find how long will it take joe to climb from street level to the roof of the sears tower:
- If Joe moves at 0.6 m/s in the vertical direction, the total distance he must cover is 443 meters in the vertical direction.
- The formula for average speed is now:
- Average speed = total distance / total time
- Total time = total distance / average speed
- Total time = 443/0.6
- Total time = 738.3 seconds
Therefore, it will take Joe 738.3 seconds (12.3 minutes) to climb from street level to the roof of the sears tower.
