Answer:
For this question, all we need to do is to apply the formular to calculate the distance since we already had the time which is h hours and the speed which is 400 miles per hour:
d = v × t = 400 × h
So the correct answer is number 3.
The equation that can be used to find the total distance the plane will travel in h hours is d = 400 × h
Total distance traveled by the plane = d miles
Total hours traveled = h hours
total speed of the plane = 400 miles per hour
Distance traveled = speed × time
d = 400 × h
d = 400h
Therefore, the equation that can be used to find the total distance the plane will travel in h hours is d = 400 × h
