Core Formula

Speed = Distance / Time
Distance = Speed × Time
Time = Distance / Speed

Unit Conversions

FromTo
1 km/h0.278 m/s
1 m/s3.6 km/h
1 mile/h1.609 km/h
Quick

m/s to km/h: × 3.6 (या 18/5)। km/h to m/s: ÷ 3.6 (× 5/18)।

Worked Examples

Example 1

Distance: 240 km, Speed: 60 km/h, Time?

Time = 240 / 60 = 4 hours

Example 2: Two-Speed

60 km @ 60 km/h, फिर 60 km @ 30 km/h. Average?

Total time = 1+2 = 3 hours
Total distance = 120 km
Average = 40 km/h (NOT 45)

Common SDT Questions

  • Trains crossing platforms
  • Trains passing each other (relative speed)
  • Boats and streams
  • Average speed
  • Catching up

Frequently Asked Questions

km/h को m/s में कैसे convert करें?+

× 5/18। 90 km/h = 25 m/s।

Average speed simple average क्यों नहीं?+

Slower speed पर time लंबा होता है।

Relative speed कैसे solve करें?+

Same direction: subtract। Opposite: add।

क्या non-uniform motion handle करता है?+

Constant speed assume करता है।

Velocity vs speed में फर्क?+

Speed scalar, velocity vector।

क्या formula किसी भी units पर काम करता है?+

Consistent units के साथ हाँ।
