Answer:
D (t) = 30 * t
Step-by-step explanation:
If we look closely, it would become a right triangle according to the statement, therefore:
a ^ 2 + b ^ 2 = c ^ 2
Because they give us the speed in each case, the distance would be that speed by time therefore, we know that:
a = 18 * t
b = 24 * t
c = d
replacing we have:
D ^ 2 = (18 * t) ^ 2 + (24 * t) ^ 2
D ^ 2 = 324 * t ^ 2 + 576 * t ^ 2
D ^ 2 = 900 * t ^ 2
D = (900 * t ^ 2) ^ (1/2)
D = 30 * t
Therefore the function of D is 30 * t
