It will take David 4 hours to walk 18 miles
Step-by-step explanation:
The formula for rate is given by:
[tex]Rate = \frac{Distance}{Time}[/tex]
Here we know,
Distance = 18 miles
Rate = 4.5
Putting the values in the formula of rate, we can find the time
So,
[tex]4.5 = \frac{18}{time}\\time = \frac{18}{4.5}\\Time = 4[/tex]
Hence,
It will take David 4 hours to walk 18 miles
