SUMMARY

The discussion revolves around calculating the time it takes for Steve Weldon to eat 5 meters of spaghetti based on his previous record of 91 meters in 29 seconds. The correct approach involves determining the rate of consumption by dividing the total distance (91m) by the total time (29s), yielding a rate of approximately 3.14 meters per second. Subsequently, to find the time for 5 meters, one must divide 5 meters by this rate, resulting in approximately 1.6 seconds. The confusion stemmed from misinterpreting the time as speed, which was clarified by participants in the discussion.

PREREQUISITES
  • Understanding of basic physics concepts such as speed, distance, and time.
  • Familiarity with the formula for calculating speed: Speed = Distance / Time.
  • Ability to perform basic arithmetic operations, including division and rounding.
  • Knowledge of unit conversion, though not necessary for this specific problem.
NEXT STEPS
  • Study the concept of rates in physics, focusing on how to derive speed from distance and time.
  • Learn about unit conversions and their applications in real-world scenarios.
  • Explore more complex problems involving rates, such as varying speeds over time.
  • Practice solving similar time-distance problems to reinforce understanding of the concepts.
USEFUL FOR

This discussion is beneficial for students learning basic physics concepts, educators teaching rate problems, and anyone interested in improving their problem-solving skills in mathematics and physics.

In 1977 Steve Weldon ate 91m of spaghetti in 29s. At the same speed how long would it take Mr. Weldon to eat 5m?

Okay, I believe they are asking for the time...so the formula would be


Time= d/V so what I did was divide the 5m by 29 and that does not make sense do I have to convert the 5m? :confused:
 
Physics news on Phys.org
Why divide by 29? Is v=29?
 
Okay after sleepinng on it I see what it is I did wrong. I was supposed to divide 91/29 to get 3.137...rounded gives me 3.14 so then I divide the 5/3.14=1.6 and that's my answer.

I solved it but I am still confused. I was assuming that 29s was my speed. It is actually my time? what is it that I am not understanding.

Please someone entertain my question. I know it may be right under my nose but I am really lost even though I solved it. I guess I just want to make sure I am reading the question correctly:frown:
 
Yes, 29 seconds is time. It is time in which he eats 91 m of spaghetti. So 91m/29s is the rate at which he eats the spaghetti, expressed in the length of spaghetti. So once, you have that rate, you can find out how long it takes him to eat any amount of spaghetti. Does that make things clearer?
