It all depends upon which helicopter you mean: 1 knot ≈ 1.15 mph A Wessex helicopter had a max speed of 115 knots, meaning it could cover 93 miles in 93 ÷ (115 x 1.15) x 60 mins ≈ 42.16 mins A Wasp helicopter had a max speed of 120 knots, meaning it could cover 93 miles in 93 ÷ (120 x 1.15) x 60 mins ≈ 40.41 mins A Sea King helicopter had a max speed of 125 knots, meaning it could cover 93 miles in 93 ÷ (125 x 1.15) x 60 mins ≈ 38.79 mins A Lynx helicopter had a max speed of 160 knots, meaning it could cover 93 miles in 93 ÷ (160 x 1.15) x 60 mins ≈ 30.31 mins Those figures are from pre 1980. A Lynx in 1986 reached 249.1 mph, meaning it could cover 93 miles in 93 ÷ 249.1 x 60 mins ≈ 22.40 mins An unofficial record of 299 mph by a Sikorsky X2 (compound helicopter) in 2010 means it could cover 93 miles in 93 ÷ 299 x 60 mins ≈ 18.66 mins
3.5 hrs + 2 hrs + 10 minutes = 5 hours and 40 minutes = 5 hours and 2/3 hours Average speed = s / t =720 miles / (5 hours + 2/3 hours) =720 miles / (17/3 hours) = 127.06 miles/hours (approximation)
The answer looks like 1.0. At first I thought you were jacking with me, but I realized that all of the numbers before 30 minutes were always rounded down and all the numbers after 30 minutes were always rounded up, regardless of the remainder. Therefore, 55 mins and 1 hour will have the same number.
distance = speed x time 75 mins = 75 ÷ 60 hours = 1.25 hours distance = 70 mph x 1.25 hrs = 87.5 miles
100m x 15 mins is 1500 metres.

first you have to convert the 6 mins to seconds 60 x 6 = 360 + 35 = 395 sooo 8550/395 = 21.65 m/s
If average for whole trip is 40mph, the trip will take 30 mins. If he has done 10 miles at 25mph this will have taken 10/25 of one hour = 24 mins, so he has 6 mins left to do 10 miles. This requires a speed of 100mph.
You would need to run at an average speed of approximately 3.61 meters per second to cover 2600 meters in 12 minutes. This is equivalent to running at a pace of around 9.58 minutes per mile.
x meters/second = 55 miles/1 hour * 1 hour/ 60 mins * 1 min/ 60 seconds = .0153 miles / second .0153 miles / second * 1,609.344 meters/1 mile = 24.6 meters/second
You will have to maintain an average speed of 4.5 mph
Speed = Distance / Time = (10 km) / (30 mins) = 0.333 km/minNow what units do you want?km/hr: (30 mins)(1 hr/60 mins) = 0.5 hr so S = (10 km)/(0.5 hr) = 20 km/hr
20 kilometers per hour or 12.5 miles/hours
First lets know the formula of average speed: average speed= distance/time taken here the distance: 1500 m and time taken: 4 minutes (the metre unit always should be with second unit) So lets convert 4 mins into sec: 4*60= 240sec average speed: 1500/240 = 25/4 = 6.25m/s

8 to 10 minutes Im a 12 year old girl and i do it in ruffly 5 mins so 8 to 10 mins would be for a non swimmer as i swim 4 hours a week.
