Speed of a body is the distance covered by the body in unit time.
Therefore Speed=
\dfrac{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 .
Speed is in Kilometer per hour (Km/h);time must be in hour
3. In order to find time, if:
Speed is in Kilometer per hour (Km/h), distance must be in Kilometer.
Speed is in metre per second(m/s), distance must be in metre.
Answer:
Metres a bus travel in per hour=900m
time taken by bus to travel 900 in per hour=30min
its speed
=900m/30min
=30km per hour
answer
a bus travel 30 km and a per hour speed
