Convert all of them to meters.
1 km = 1000 meters
6 * 1000 = 6000
6 km = 6000 m
1 cm = 0.01 m
600 * 0.01 = 6
600 cm = 6 m
1 mm = 0.001 m
6000 * 0.001 = 6 m
So we have:
6000 m, 60 m, 6 m, and 6 m.
So 6 kilometers is the greatest.
Answer:
40 mph
Step-by-step explanation:
We assume "outbound" refers to the trip <em>to the lake</em>. The ratio of speeds is inversely proportional to the ratio of times, so ...
outbound speed : inbound speed = 4 : 3
These differ by one ratio unit, so that one ratio unit corresponds to the speed difference of 10 mph. Then the 4 ratio units of outbound speed will correspond to ...
4×10 mph = 40 mph
Paul's average speed on the outbound trip was 40 mph.
___
The distance to the lake was 120 mi.
Answer:
150
Step-by-step explanation:
We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other.

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
24y=100(36)
24y=3600
y=150.
There are 150 students in the choir.
