Jada eats 2 scoops of ice cream in 5 minutes. Noah eats 3 scoops of ice cream in 5 minutes. How long does it take them to eat on

Scrat [10]

Answer:

$\frac{5}{6}$ minutes

Step-by-step explanation:

Let's find unit rate of each.

<u>Jada</u>

2 scoop in 5 minutes

So,

1 scoop in 5/2 = 2.5 minutes

<u>Noah</u>

3 scoop in 5 minutes

So,

1 scoop in 5/3 = 1.25 minutes

These are the times. Time and rate are inverses of each other. So the rates of each is:

Jada = 1/2.5 = 0.4

Noah = 1/1.25 = 0.8

Working together, we add the rates and find the time:

(0.4+0.8)*t = 1

1.2t = 1

t = 1/1.2 = $\frac{5}{6}$ minutes

So, they take $\frac{5}{6}$ minutes to eat one scoop, working together

Units of Capacity

marysya [2.9K]

Answer:

$\large\boxed{\large\boxed{0.2deciliter}}$

Explanation:

Build your conversion factors using the conversion table:

$1 cup = 0.237 liters\implies 1=0.237liters/1cup$

From the prefixes used in the metric system, you know that 1 deciliter = 0.100 liters. Then:

$1 deciliter = 0.100 liters\implies 1=1deciliter/0.100liters$

Arrange the expression to simplify the units and convert from cups to deciliters:

$9cups\times 0.237liters/cup\times 1deciliter/0.100liters=0.2133deciliter$

Round to the nearest tenth: 0.2 deciliter.
