Alright, let's break down the problem step-by-step.
1. Understand Jeff's Speed:
- Jeff runs at a speed of 7 kilometers per hour.
2. Understand Cameron's Speed:
- Cameron runs at a speed of 100 meters per minute.
3. Convert Cameron's Speed to the Same Units as Jeff's Speed:
- Jeff's speed is given in kilometers per hour, so we need to convert Cameron's speed from meters per minute to kilometers per hour for a fair comparison.
- We know that:
- 1 kilometer = 1000 meters
- 1 hour = 60 minutes
- Cameron's speed in meters per minute: 100 meters per minute.
- Convert meters per minute to kilometers per hour:
1. First, convert meters to kilometers:
[tex]\[
100 \text{ meters} = 0.1 \text{ kilometers}
\][/tex]
2. Since Cameron runs 0.1 kilometers in 1 minute, we need to find out how many kilometers he would run in 1 hour:
[tex]\[
\text{Cameron's speed in kilometers per hour} = 0.1 \text{ kilometers per minute} \times 60 \text{ minutes per hour}
\][/tex]
[tex]\[
= 6 \text{ kilometers per hour}
\][/tex]
4. Compare Jeff's Speed and Cameron's Speed:
- Jeff's speed: 7 kilometers per hour.
- Cameron's speed: 6 kilometers per hour.
5. Determine Who is Faster:
- Since 7 kilometers per hour (Jeff's speed) is greater than 6 kilometers per hour (Cameron's speed), Jeff is faster.
Hence, the answer is:
(A) Jeff is faster than Cameron.
