To find the missing values - t and t² - we can use the equations of motion.

First, we can use the equation v = s/t, where v is the velocity, s is the displacement, and t is the time.

For the first segment: V¹ = 90 km/h Sag for V¹ = t₁ t₁ = S/v₁ = 1170 km / 90 km/h = 13 hours

Next, for the second segment: V² = 275 km/h Sag for V² = t₂

To find t₂, we need to find the time taken to cover the remaining distance (1170 km - sag for V¹).

Remaining distance = S - sag for V¹ = 1170 km - 13 hours * 90 km/h = 180 km

t₂ = remaining distance / V₂ = 180 km / 275 km/h = 0.65 hours

Finally, to find t²: t² = (t₁ + t₂)² = (13 hours + 0.65 hours)² = 13.65 hours²
