Speed, time aur distance ke important tricks hindi me

Speed, time and distance mathematics ke ek important topic hai. Aaj hum time and distance ke kuch important method and shortcuts tricks ki bare me hindi me jankari hasil karenge.
Distance(D) = Speed(S) x  Time(T) ya speed, time and distance ke main sutra hai.

Time and distance ke question ke solution kam samai me solve karne ki liye niche diye gaye chart ko yaad karligiye.

                      Per hour Speed                                             Per second speed
                           18 km.                                                               5 m.
                           36 km.                                                             10 m.
                           54 km.                                                             15 m.
                           72 km.                                                             20 m.
                           90 km.                                                             25 m.
                         108 km                                                              30 m.

Agar up upper diye gaye chart ko  dekhe to aap dekhenge ki agar speed/hour 9 ke multiple hua, tube uss bastu ka speed 2.5 ke multiple hoga.
Agar kisi bastu ka speed 27 km / h hua ,tube second me speed = (2.5 x 3) = 7.5 metres hoga because 27 ,  9 ke 3 guna hai.

Example: How long will a train105 m. long travelling  54 km./h take to pass amile stone?

Solution: Upper diye hua chart ki hisab se agar train ke speed 54 km./ h hua to chart ke hisab se speed second me hoge 15 m.
Milestone cross karne ki matlab train ke lambai kitne hai ye batate he.
Trian milstone ko cross karege  = 105/15 = 7 seconds

Agar speed per hour  9 ke multiple nahi hua tube bastu ka Speed second me nikalne ke liye niche diye gaye sutra ki isstemal karenge

kuch important sutra ki jankari hindi me:

• Trick(1):  Per second speed = (Per hour speed  X  5/18) m./s. and

 Per hour speed = (per second speed X 18/5) km./h

Example: Express train of 18 km./hr in metres per second.
Soln:  Per second speed = (18 X 5/18) = 5 m./sec.

Example: Express 10 m./sec. in km./ hr.
Soln: Per hour speed = (10 X 18/5 )  = 36 km./ hr.
upper diye gaye isse sutra ke madad se kisi ve number ke   km/hr and m./ sec. nikale ja sakte hai.
