You have to add all three concerts 953+1100+1100 =3,163
And the answer you have divided by 3
The average of people at the concerts were 1,054
If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
Let
be the smaller integer. The larger integer is then
, and we have






We omit
, since
is negative.
Then for
we find
, but this is not odd.
There are no consecutive odd integers that satisfy the given condition!
Answer:
2000 meters
Step-by-step explanation:
When the motorboat is moving downstream, its speed relative to the ground is 18 km/h, so its speed relative to the raft is 15 km/h.
When the motorboat is moving upstream, its speed relative to the ground is 12 km/h, so its speed relative to the raft is again 15 km/h.
Converted to m/min, the relative speed is:
15 km/h × (1000 m/km) × (1 h / 60 min) = 250 m/min
It takes the motorboat 16 minutes to travel to the front of the raft and back. Since the speed is the same in both directions, the motorboat takes 8 minutes to travel the length of the raft.
So the length of the raft is 250×8 = 2000 meters.
