Answer 2

Answer:

2.5 mph

Step-by-step explanation:

Speed = $\frac{Distance}{Time}$

Since the question demands that the speed is in miles per hour, we should convert 96 minutes into hours.

Just divide 96 by 60.

∴ Time = $\frac{96}{60}$ hours

∴ Speed = $\frac{4}{\frac{96}{60}}$

               = 4 ×  $\frac{60}{96}$

               = $\frac{5}{2}$

               = 2.5 mph
