The formula to calculate the speed of an object is :
Distancetime
DistancexTime
TimeDistance
Hence, option (a) is correct.
The formula to calculate speed of an object is Speed=Distance(d)Timetaken(t)..
what is the formula to calculate density of an object ?
An object starts with initial velocity u and attains velocity v. The velocity change in itself to a uniform rate. What is the formula to calculate average speed in this situation ?
