Explanation:

Step1: Find the speed

Speed = Distance / Time. Given distance \(d = 21\) miles and time \(t=3\) hours.
Speed \(v=\frac{21}{3}=7\) miles per hour.

Step2: Calculate the distance in 4 hours

Using the formula \(d = v\times t\), with \(v = 7\) miles per hour and \(t = 4\) hours.
\(d=7\times4 = 28\) miles.

Answer:

28 miles
