Speed of a body is the distance covered by the body in unit time.

Speed of a body is the distance covered by the body in unit time.Therefore Speed=

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:Distance = Speed \times Time

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:Distance = Speed \times Time Time = \dfrac{Distance}{Speed}

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:Distance = Speed \times Time Time = \dfrac{Distance}{Speed} 1. In order to find speed, if :

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:Distance = Speed \times Time Time = \dfrac{Distance}{Speed} 1. In order to find speed, if :Distance is in metre (m) and time in second (s); then the speed is in metre per second (m/s)

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:Distance = Speed \times Time Time = \dfrac{Distance}{Speed} 1. In order to find speed, if :Distance is in metre (m) and time in second (s); then the speed is in metre per second (m/s)Distance is in Km (Km) and time in hour (h); then the speed is in Kilometer per hour (Km/h)

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:Distance = Speed \times Time Time = \dfrac{Distance}{Speed} 1. In order to find speed, if :Distance is in metre (m) and time in second (s); then the speed is in metre per second (m/s)Distance is in Km (Km) and time in hour (h); then the speed is in Kilometer per hour (Km/h)2. In order to find the distance, if:

Speed of a body is the distance covered by the body in unit time.Therefore Speed= {Distance}{Time} which implies:Distance = Speed \times Time Time = \dfrac{Distance}{Speed} 1. In order to find speed, if :Distance is in metre (m) and time in second (s); then the speed is in metre per second (m/s)Distance is in Km (Km) and time in hour (h); then the speed is in Kilometer per hour (Km/h)2. In order to find the distance, if:Speed is in metre per second (m/s); time must be in second .

In order to find speed, if :Distance is in metre (m) and time in second (s); then the speed is in metre per second (m/s)Distance is in Km (Km) and time in hour (h); then the speed is in Kilometer per hour (Km/h)2. In order to find the distance, if:Speed is in metre per second (m/s); time must be in second .Speed is in Kilometer per hour (Km/h);time must be in hour
