450km is about 280 miles.
If I can travel 450 miles in 2 hours, I can travel 450 ÷ 2 = 225 miles in 1 hour. As I can travel 225 miles in each hour, I can travel 1200 miles in: 1200 ÷ 225 = 51/3 hours = 5 hours 20 minutes.
time = distance / speed so, 450 miles / 100 mph = 4.5 hours
To travel 200 miles at 450 mph takes 26 min 40 sec. time = distance / speed = 200 miles / (450 miles / hour) = 4/9 hour ≈ 0.444 hour 1 hour = 60 min → 4/9 hour = 4/9 × 60 min = 26 2/3 min ≈ 26.667 min 1 min = 60 sec → 2/3 min = 2/3 × 60 sec = 40 sec
