Answer:
1. If we drink 8 glasses, we are drinking 2 L of water, so we are exceeding 1 L of water per day.
2. We need 100 sections.
I used metric conversion to convert km to meters.
3. 230 mL of lemonade per person
I used metric conversion to convert L to ML
Explanation:
1. 250 mL = 1 glass
We are drinking 8 glasses
8 glasses * 250 ml/ 1 glass = 2000 mL
1 L = 1000 mL
2000 mL * 1 L/1000 mL =2 L
If we drink 8 glasses, we are drinking 2 L of water, so we are exceeding 1 L of water per day.
I used metric convertsion to convert mL to liters.
Guardrails sections to be 5m long
Road length that needs a guardrail is .5 km. We need to convert this to meters 1000 m = 1 km
.5km * 1000m / 1km = 500 meters
We have 500 meters that needs guardrails.
500 meters * 1 section/ 5 meters = 100 sections
We need 100 sections.
I used metric conversion to convert km to meters.
3. 6.9 L of lemonade to serve 30 people. We want to serve ml
Convert L to mL
1L = 1000 ML
6.9 L * 1000 ml/1L = 6900 mL
We need to divide 6900 Ml by 30 people
6900mL/30 people = 230 mL of lemonade per person
I used metric conversion to convert L to ML
