1 kilometer = 1000 meters.
Multiply total kilometers by 1000:
108 kilometers x 1000 = 108,000 meters.
1 hour = 3600 seconds.
Divide total meters by 3600:
108,000 / 3600 = 30 meters per second
Multiply 30 meters per second by 15 seconds:
30 x 15 = 450 meters in 15 seconds.
Answer:
39 dimes
Explanation:
From the graph:
• Total number of nickels = 9+4+7=20
,
• Total number of dimes = 7+10+9 = 26
The ratio of total nickels to total dimes = 20:26
If the total number of nickels the students donate is increased to 30, we have:

We then solve for x:

The number of dimes they should donate to keep the ratio of total nickels to total dimes the same is 39.
