C. 2 mph
Explanation:
speed equals total distance covered in total time of of travel
since,
total distance = 4 miles
time taken = 2 hrs
speed = 4m / 2hrs =2mph
Answer: C. 2mph
Explanation:
Speed is the rate of change in distance. Since distance has to do with how far an object has gone, it means we will only take consideration of how far she has walked which is 4miles.
Mathematically, Speed = Distance/time
Given distance = 4miles and time = 2hours
Speed = 4miles/2hours
= 2miles/hour i.e 2mph
