SUMMATIVE TEST NO.1

Problem Solving

MELC 1: Describe the motion of an object in terms of distance or displacement, speed or velocity,

and acceleration.



Direction: Using the given formulas and the steps of problem solving, solve the following

problems:

Speed = distance Distance =speed x time Time= distance

time d = s( m/s) x t(s) speed

s= d(m) d = m t = d(m)t (s) for example : d= 5m/s x 10 s s (m/s)

for example: s= 50m d= 50 m t= s

10 s for example: t= 50m

S= 5m/s 5m/s

t = 10 s
