The value of d when h is 500m is approximately 1,813m
Give the heights above the ground (hm) after it has dropped expressed as:
h = 3/8(d-480),
If h = 500m, then;
500 = 3/8(d - 480)
Cross multiply
500*8 = 3(d - 480)
4000 = 3(d - 480)
Expand to have:
4000 = 3d - 1440
3d = 5440
d = 1,813.3m
Hence the value of d when h is 500m is approximately 1,813m
