Answer:
d = 4 + 4h
Step-by-step explanation:
According to question d is the total distance from Laura's house at time h .
Initial distance from house = 4 miles
speed of Laura = 4 miles per hour
formula for distance = speed * time
distance covered when time is h hours = 4 miles per hour * h hours
= 4h miles
Total distance from house is given as d, hence
d = Initial distance from house (4 miles) + distance covered when time is h hours (4h miles)
d = 4 + 4h
Thus, an equation to model this situation is d = 4 + 4h .
