Three elephants are standing on a very strong bridge. The bridge happens to have marks at every meter along the way. Elephant #1 is standing at 4m and starts walking. He walks for 30 seconds and after 30 seconds, the elephant is at the place on the bridge marked 64 meters. What is Elephant #1’s speed?

Understand the Problem

The question is asking to find the speed of Elephant #1 based on his walking distance and time. We know he starts at 4 meters and walks for 30 seconds to a position marked at 64 meters.

Answer

The speed of Elephant #1 is $2 \text{ m/s}$.
Answer for screen readers

The speed of Elephant #1 is $2 \text{ m/s}$.

Steps to Solve

  1. Calculate Total Distance Walked To find Elephant #1's speed, we first determine how far he walked. He starts at 4 meters and ends at 64 meters. The distance walked is: $$ \text{Distance} = 64 \text{ m} - 4 \text{ m} = 60 \text{ m} $$

  2. Identify Time of Travel The time that Elephant #1 walked is provided as 30 seconds.

  3. Calculate Speed Speed is calculated using the formula: $$ \text{Speed} = \frac{\text{Distance}}{\text{Time}} $$ Substituting the values we found: $$ \text{Speed} = \frac{60 \text{ m}}{30 \text{ s}} = 2 \text{ m/s} $$

The speed of Elephant #1 is $2 \text{ m/s}$.

More Information

The speed is a measure of how quickly an object changes its position. In this case, the elephant covered a significant distance in a relatively short amount of time, illustrating basic principles of motion.

Tips

  • Miscalculating the distance by not subtracting the starting position from the ending position.
  • Confusing units of measurement; ensure the distance and time are in compatible units (meters and seconds).
