Question

Tinley is training to run a half-marathon. She sets a pace so that every mile takes 77 minutes. Write an equation for the amount of time, tt, it takes Tinley to run mm miles.

Answer 1

An equation for the amount of time t , it take Tinley to run m miles is ,
`t = 7m`

Explanation:

Using distance formula:

`\text{Distance} = \text{Speed} * \text{time}`

From the given information:

She sets a pace so that every mile takes 7 minutes

⇒
`\text{speed} = (1)/(7) \text{mile per minute}`

To find an equation for the amount of time t, it takes Tinley to run m miles.

Using above formula:

Substitute the given values we have;

`m = (1)/(7) * t`

Multiply 7 both sides we have;

`7m = t`

Therefore, an equation for the amount of time t , it take Tinley to run m miles is ,
`t = 7m`
