The equation for difference in altitude of the two helicopters is A = 650 - 100t

Step-by-step explanation:

Given;

The altitude of one helicopter is, A1 = 600 + 150t

The altitude of a second helicopter is, A2 = 1250 + 50t

Their difference in altitude, A at time t, is calculated as

A₂ - A₁ = A = (1250 + 50t) - (600 + 150t)

A₂ - A₁ = A = 1250 + 50t - 600 - 150t

A₂ - A₁ = A = 1250 - 600 + 50t - 150t

A₂ - A₁ = A = 650 - 100t

Therefore, the equation for difference in altitude of the two helicopters is A = 650 - 100t
