Answer:

10

Step-by-step explanation:

10 workers working 2 hours a day is 2*10=20 work hours per day

2 workers working 5 hours a day is 2 *5=10 work hours per day

Per day 1/2 as many work hours so will take 2 times as long.

5*2 = 10 days

IceJOKER [234]

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

Step-by-step 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
