Speedof light: 299,792,458 m/s; Time traveled: 100 seconds; You can perform the calculation in three steps: Determine the speed of light. As mentioned, the speed of light is the fastest speed in the universe, and it is always a constant in a vacuum. Hence, the speed of light is 299,792,458 m/s. Determine the time that the light has traveled.
Adistance of 1.4 Km is covered in 10 min , then speed=_____Km/min; A distance of 32 Km is covered in 1.6 hrs , then speed=_____Km/min; A and B start from the same point and at the same time with speeds 15 Km/h and 12 Km/h respectively . Find the distance between A and B after 6 hours if both move in: i)same direction ii) opposite

Concept V B = Velocity of Boat in km/hr = 5 km/hr. V x = Velocity of river in km/hr. The resultant of Boat velocity & river velocity gives time to cross the river along the shortest possible path is 15 min. V B x = V B 2 + V x 2. t i m e = S

Now using the formula of time = distance/speed = 100 km/40 km/hr = 5/2 hours = 5/2 × 60 minutes, (Since 1 hour = 60 minutes) = 150 minutes. 2. Victor covers 210 km by car at a speed of 70 km/hr. find the time taken to cover this distance. Solution: Using the unitary method; 70 km is covered in 1 hour. SpeedCalculator. - Km per minute. Our online tools will provide quick answers to your calculation and conversion needs. On this page, you can calculate average speed in km per minute. Distance: Time: h min s.
Downstreamspeed of boat = Speed of boat in still water + Speed of stream. Formula used: S = D/T (Where S = Speed, D = Distance, and T = Time) Calculation: ⇒ The speed of boat in downstream = 15 + 3 = 18 km/h = 18/60 km/minutes = 0.3 km/minutes. ⇒ The distance travelled in 12 minutes in downstream = 0.3 × 12 = 3.6 km

A 5 km/hr. B. 3 km/hr. C. 7 km/hr. D. 9 km/hr. Answer & Explanation. Q.4. A boat travels from point A to B, a distance of 12 km. From A it travels 4 km downstream in 15 minutes and the remaining 8 km upstream to reach B. If the downstream speed is twice as high as the upstream speed, what is the average speed of the boat for the journey from A
