One20-minute walk per day, at a brisk pace, will boost you from the deadly "inactive" category. This type of walk will cover at least one mile and add 2000 to 3000 steps to your daily step count. It will burn 70 to 100 calories, depending on your weight. A large study showed that a brisk 20-minute walk each day could reduce the risk of early

MPM= Walking speed (in meters per minute) FG = Walking surface grade (expressed as a fraction, i.e. 6% = .06) WKG = Weight (in kilograms) T = Time (in hours) The units for the constant 3.5 are milliliters of oxygen per kilogram per minute. The units for the constant 60 are minutes per hour. The units for the constant 5 are calories per liter

Aboat, which has a speed of 5 km / h in still water, crosses a river of width 1 km along the shortest possible path in 15 minutes. What is the magnitude of velocity of the river water? A. 5 km / hB. 3 km / hC. 6 km / hD. 4 km / h Solution Step 1: The formula for distance is. Distance = Rate × Time. Total distance = 50 × 3 + 60 × 2 = 270. Step 2: Total time = 3 + 2 = 5. Step 3: Using the formula: Answer: The average speed is 54 miles per hour. Be careful! You will get the wrong answer if you add the two speeds and divide the answer by two.

Alight-year, alternatively spelt light year, (ly) is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km, which is approximately 5.88 trillion mi.As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Aboat which has a speed of 15 km/hr in still water crosses a river of width 3 km along the shortest possible path in 20 minutes. The velocity of the river water in km/hr is View Solution
Ifyou’re new to running, begin with 20- to 30-minute sessions, Or you can run at a high speed for 2 to 5 minutes followed by an equal time spent jogging. Do this 4 to 6 times.
