It is $100 because if you work it out on paper then you could have on the paper and the answer is 100$
Answer:
ok is very easy
Step-by-step explanation:
so 1/5 of an hour is 12 mins
and 2 is 2 hrs so that 120 mins
now add 120+12=132
132 x -30 degrees
The answer to that is 132 x -30 =
-3960 sorry if its wrong and if you get a second try put -69.1150384 rad
I think sorry if you get it wrong have a good day
The average speed of Martha and Sarah is 32 km/h.
We need to know about the speed to solve this problem. Speed can be determined as the distance traveled divided by time. It can be written as
v = s / t
where v is speed, s is distance and t is time.
From the question above, we know that:
t sarah = 3 hours
t martha = 5 hours
v sarah = 40 km/h
By using the speed equation, we get the distance
vsarah = s / tsarah
40 = s/3
s = 120 km
Find Martha's speed
vmartha = s / tmartha
vmartha = 120 / 5
vmartha = 24 km/h
Find average speed
v = (vsarah + vmartha)/2
v = (40 + 24) / 2
v = 32 km/h
Hence, the average speed of Martha and Sarah is 32 km/h.
