Solution by Steps
step 1
Convert the given split rate to a rowing rate in meters per minute
step 2
The split rate is 2 min500 m\frac{2 \text{ min}}{500 \text{ m}}. To find the rowing rate in mmin\frac{\text{m}}{\text{min}}, take the reciprocal of the split rate
step 3
The reciprocal of 2 min500 m\frac{2 \text{ min}}{500 \text{ m}} is 500 m2 min\frac{500 \text{ m}}{2 \text{ min}}
step 4
Simplify the reciprocal to find the rowing rate: 500 m2 min=5002×mmin\frac{500 \text{ m}}{2 \text{ min}} = \frac{500}{2} \times \frac{\text{m}}{\text{min}}
step 5
Using the asksia-ll calculation list, we know that 500÷2=250500 \div 2 = 250
step 6
Therefore, the rowing rate is 250mmin250 \frac{\text{m}}{\text{min}}
Answer
250mmin250 \frac{\text{m}}{\text{min}}
