The train travels at 5.5km per hour.
We know that in x hours it will advance by x*5.5 km.
Hence we need to solve x*5.5=82.5, hence x=82.5/5.5=15
It will take 5 hours
Answer:
Step-by-step explanation:
We can use the exponential growth formula:
y = a(1 + r)ˣ
where
y = amount after x time
a = initial amount
r = growth rate as a decimal fraction
x = years since 2013
Data:
y = 2300
r = 0.12
x = 2022 - 2013 = 9
Calculations:
x = 2022 - 2013 = 9
The figure below shows the growth curve for dengue victims since 2013
This is how you solve the three questions. hope this helps.
