Jake runs fastest
Step-by-step explanation:
The given is:
- Emily Runs 10 ft./s
- Jake runs 334 feet in 26 seconds
- Katie runs 1 mile in 596 seconds
- Stephanie runs 580 feet in one minute
We need to find who runs fastest
To solve the problem we must to find the unit rate of each one in feet per second
∵ Jake runs 334 feet and 26 seconds
- To find the unite rate divide 334 feet by 26 seconds
∴ Jake's rate = 334 ÷ 26 = 12.85 ft./s
∵ Katie runs 1 mile in 596 seconds
- Change the mile to feet
∵ 1 mile = 5280 feet
∴ Katie runs 5280 feet in 596 seconds
- To find the unite rate divide 5280 feet by 596 seconds
∴ Katie's rate = 5280 ÷ 596 = 8.86 ft./s
∵ Stephanie runs 580 feet in one minute
- Change the minute to seconds
∵ 1 minute = 60 second
∴ Stephanie runs 580 feet in 60 seconds
- To find the unite rate divide 580 feet by 60 seconds
∴ Stephanie's rate = 580 ÷ 60 = 9.67 ft./s
∵ Emily's rate is 10 ft./s
∵ Jake's rate is 12.85 ft./s
∵ Katie's rate is 8.86 ft./s
∵ Stephanie's rate is 9.67 ft./s
- The fastest one who has the greatest rate
∵ Jake's rate is the greatest
∴ Jake runs the fastest
Jake runs fastest
