Math Problem Statement
Question 7 options: Solve this problem.
In 1991, American sprinter Carl Lewis set a world record of 9.86 seconds for the 100-meter dash. A honeybee can fly the same distance in 20.706 seconds. How many times faster than a honeybee is Carl Lewis?
Solution
To find how many times faster Carl Lewis is than a honeybee, we need to compare their speeds. Speed is calculated as:
Step 1: Calculate Carl Lewis's speed
The distance Carl Lewis runs is 100 meters, and the time he takes is 9.86 seconds.
Step 2: Calculate the honeybee's speed
The distance the honeybee flies is also 100 meters, and the time it takes is 20.706 seconds.
Step 3: Find how many times faster Carl Lewis is
Now, we divide Carl Lewis's speed by the honeybee's speed:
Final Answer:
Carl Lewis is approximately 2.1 times faster than a honeybee.

- How would the result change if Carl Lewis ran 110 meters instead of 100?
- What is the speed of a cheetah over the same distance compared to Carl Lewis?
- How much faster would Carl Lewis need to run to break the 9.5-second barrier?
- If Carl Lewis maintained this speed over 400 meters, what would his time be?
- How much time would the honeybee need to travel 200 meters at the same speed?
Tip: When comparing speeds, it's often helpful to calculate how long each would take for the same distance to make direct comparisons easier.
