barbara can walk 3200 meters in 24 minutes.Mavis can walk 11,808 feet in 24 minutes.Who walks at a faster rate of speed?Explain the steps you take to solve the problem.
3200 meters = 10498.69 feet
To determine who walks at a faster rate of speed, we need to convert the distances traveled by Barbara and Mavis to a common unit of measurement, such as meters or feet per minute.
1. Convert Mavis's distance from feet to meters:
- Since 1 meter is equal to approximately 3.281 feet, we can divide Mavis's distance by 3.281 to convert it to meters.
- 11,808 feet ÷ 3.281 = 3597.6 meters (rounded to one decimal place)
2. Now that both distances are in meters, we compare the rates of speed:
- Barbara can walk 3200 meters in 24 minutes, so her speed is 3200 meters ÷ 24 minutes = 133.33 meters/minute (rounded to two decimal places).
- Mavis can walk 3597.6 meters in 24 minutes, so her speed is 3597.6 meters ÷ 24 minutes = 149.9 meters/minute (rounded to one decimal place).
Therefore, Mavis walks at a faster rate of speed since she can cover approximately 149.9 meters per minute, while Barbara can cover approximately 133.33 meters per minute.
