Answer:

The rate is 1.75 feet/seconds or 105 feet/minute.

Explanation:

Given that,

Li walks at a constant rate of 7 feet in 4 seconds

To find the constant of proportionality, divide 7 feet by 4 seconds.

So,


k=\frac{7\ \text{feet}}{4\ \text{seconds}}\\\\k=1.75\ \text{ft/s}

1.75 ft/s is the constant of proportionality

We know that, 1 minute = 60 seconds

k = 105 feet/minute

So, the rate is 1.75 feet/seconds or 105 feet/minute.
