Question

Seth traveled 1 mile in a go cart in 1 1/4 minutes. How fast is Seth traveling in miles per hour?

Answer 1

Divide the traveled distance over the total time it took to travel it to find the rate in miles per minute:

`\frac{1\text{ mile}}{1+(1)/(4)\text{ minutes}}=\frac{1\text{ mile}}{1.25\text{ minutes}}=0.8\text{ miles per minute}`

Since each hour has 60 minutes, multiply that rate by 60 to find how fast is Seth in miles per hour:

`0.8*60=48`

Therefore, the rate of distance to time for Seth is:

`48\text{ miles per hour}`
