Time and Distance Questions Answers Formulas, Tips and Tricks

• 1. Important formulae and facts of Time and Distance

  
  

  1. Formula of Speed
  
  Speed = \begin{aligned} \left(\frac{Distance}{Time} \right) \end{aligned}
  
  So Formula of speed is, speed is equal to distance upon time. If you remember this formula then you will learn next two formulae two.
  
  2. Formula of Time
  
  Time = \begin{aligned} \left(\frac{Distance}{Speed} \right) \end{aligned}
  
  So Formula of time is, time is equal to distance upon speed.
  
  3. Formula of Distance
  
  Distance = (Speed * Time)
  
  So distance is simply speed into time. All three formulae that formula of speed, formula of time and formula of distance are interrelated.
  
  4. Convert from kph(km/h) to mps(m/sec)
  For converting kph(kilometre per hour) to mps(meter per second) we use following formula
  
  \begin{aligned}
  x&km/hr = \left(x*\frac{5}{18}\right)m/sec
  \end{aligned}
  
  6. Convert from mps(m/sec) to kph(km/h)
  For converting mps(meter per second) to kph(kilometre per hour) we use following formula
  
  \begin{aligned}
  x&m/sec = \left(x*\frac{18}{5}\right)km/h
  \end{aligned}
  
  
  7. If the ratio of the speeds of A and B is a : b, then the ratio of the
  
  the times taken by then to cover the same distance is
  \begin{aligned} \frac{1}{a}:\frac{1}{b} & or & b:a \end{aligned}
  
  8. Suppose a man covers a certain distance at x km/hr and an equal distance at y km/hr. Then,
  
  the average speed during the whole journey is
  \begin{aligned} \frac{2xy}{x+y} \end{aligned}
