Sagot :
Answer:
DIVISION
1•S=D/T
S=10m/25sec
S=0.4m/s
DIVISION
2•T=D/S
T=30m/10m/sec
T=3 sec
MULTIPLICATION
3•D=T x S
D=90 sec x 1 m/sec
D=90m
DIVISION
4•S=D/T
S=45km/2h
S=22.5 or 23km/h ROUND OFF
MULTIPLICATION
5•D=T x S
D=30sec x 3m/sec
D=90m
Explanation:
Formula of Speed:
s=d/t or s=d divided by t
Formula of Distance:
d=s x t or d=s times t
Formula of Time:
t=d/s or t=d divided by s
