∙ 11y agoTo find the speed in km per hour, divide the distance by the time taken. First, convert the time to hours: 4 hours and 48 minutes is equal to 4.8 hours. Then, divide the distance (203 km) by the time (4.8 hours) to get the speed: 203 km / 4.8 hours = 42.29 km/hr.
Thallium-203 has a half-life of approximately 1.4 minutes. Half-life is the time it takes for half of the radioactive material to decay.
The atomic mass of thallium-203 is 203 amu (atomic mass units), and the atomic mass of thallium-205 is 205 amu.
The highest recorded wind speeds on Uranus have been measured at approximately 560 miles per hour (900 kilometers per hour) in its upper atmosphere. Uranus is known for its extreme and variable wind speeds due to its unique axial tilt and lack of a solid surface.
14.5 stone = 203 pounds
203 kilograms is equivalent to approximately 448 pounds.
This is an average speed of 26.3 miles per hour.
I used Google to get that. But if you actually want to LEARN how to do it, pay attention. Convert 48 minutes to hours by dividing by 60 (minutes per hour). That gives you 0.8. So, 4 hours and 48 minutes is the same as 4.8 hours (4 + 0.8). Now, divide the distance, 203 km, by the time, 4.8 hours, which gives you your answer in km/hr.
203 minutes = 3.38333333 hours
203 km = 203 x 5/8 miles = 126.875 miles; to get mph, divide 126.875 by 4 and 4/5 = 26.43 mph.
Time = Distance/Speed = 203/75 = 2.7 hours approx or 2 hours 42 minutes, approx.
3 hours and 23 minutes.
Speed = Distance/Time Rearrange the formula: Time = Distance/Speed Time = 203/59 = 3.440677966 hours or about 3 hours and 26 minutes.
distance = rate * time rate = distance / time 1 kilometer = 1000 meters 4 hours and 48 minutes = 288 minutes * 60 seconds/minute = 17280 seconds 203 km * 1000 meters/km / 17280 seconds ~= 11.75 meters per second
mph= miles per hour kph=kilometers per hour The Mallards top speed is 126 MPH (203 kph
That's about 26.3 miles per hour.
At 60 miles per hour it would take about 4 hours.
3.23 X 60 = 193.8 min OR if you meant 3 hours and 23 minutes (3 X 60)+23= 203 min
