The SIFT’s Math Skills Test (MST) emphasizes proportional reasoning, unit rates, and multi-step word problems. Here, the route is 180 miles, split into two equal legs of 90 miles each. Time = Distance ÷ Speed. For leg 1: 90 nm ÷ 120 kt = 0.75 hr = 45 minutes. For leg 2: 90 nm ÷ 90 kt = 1.0 hr = 60 minutes. Total = 45 minutes + 60 minutes = 105 minutes = 1 hour 45 minutes. That corresponds to 1:45. However, read carefully: the question asks for total flight time for the entire 180 miles. Wait—re-check the arithmetic: 90/120 = 0.75 hr (45 min) and 90/90 = 1.0 hr (60 min). Summed, that is indeed 1 hr 45 min. But option C says 2 hr 00 min; that seems to conflict. To avoid a trap, we verify again: 105 minutes total equals 1 hr 45 min, which is option B. Yet the correct SIFT approach also tests attention to detail—since equal distances were stated, the arithmetic above stands. Therefore, 1:45 is correct. (Note: Choose B.)
