2 hours 18 minutes.
5 hr 20 min.
At least 1 hour, 46 minutes, 48 seconds at 90 miles per hour.
7 hours.
Dividing distance by speed gives 160/80 = 2. Therefore, it would take 2 hours to travel 160 kilometres at 80 miles per hour.
Assuming you mean 1120 miles then:time = distance ÷ speed⇒ time = 1120 miles ÷ 160 mph= 7 hours
Time = Distance/Speed = 160/80 = 2 hours
160/30 = 16/3 = 5 and 1/3 hours
Time = 350 miles / 160 miles per hour Time ≈ 2.1875 hours However, to express the time in minutes, it's more convenient to convert the decimal part: 2.1875 hours * 60 minutes per hour ≈ 131.25 minutes Therefore, the helicopter will take approximately 131 minutes, or 2 hours and 11 minutes to travel 350 miles at 160 mph.
Do the math - 80 miles per hour, that's 160 miles in two hours. 160 is 10 percent of 1600, so....20 hours
If you travel 160 miles in 3 hours, your average speed is 53 and one-third miles per hour.
