I think
A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
Answer:
2.6%
Step-by-step explanation:
Given the current CPI = 231.56
Previous CPI (CPI a year ago) = 225.3
Rate of inflation over the past year = current CPI - previous CPI/previous CPI × 100%
Rate of inflation = 231.56-225.3/225.3 × 100%
5.86/225.3× 100%
= 2.6%
Rate of inflation over the past year will be 2.6%
