Answer:

63.8 miles

Step-by-step explanation:

If the train travels 4.4 miles in 4 minutes, then you have to divide 4.4/4 to find the miles the train travels per minute.

4.4/4 = 1.1

So, since the train travels 1.1 miles per minute, and we want to know how fast it travels in 58 minutes, we have to multiply 1.1 by 58. Since 1.1 is a decimal number, we have to multiply both sides by 10 to get 11x580.

11x580 = 5800+ 580 = 6380

Since we multiplied both numbers by 10, we have to divide 6380 by 100.

6380/100 = 63.8

So, the train travels 63.8 miles in 58 minutes.

Answer:

A) $\frac{3}{12}$

Step-by-step explanation:

Given:

Jing is helping the kindergarten teacher put together bags of crayons.

Each bag has 4 crayons, and 1/4 of the crayons in each bag are green.

What fraction of the crayons in 3 bags are green?

<u>Solution:</u>

1 bag contains number of crayons = 4

1 bag contains number of green crayons = $\frac{1}{4} \ of\ 4 = \frac{1}{4}\times4=1$

Total number of bags = 3

Total number of crayons in 3 bags = 4 $\times$ 3 = 12

1 bag contains number of green crayons = 1

Total number of green crayons in 3 bags = 1 $\times$ 3 = 3

Fraction of the green crayons out of total = 3 out of 12 = $\frac{3}{12}$

Therefore, fraction of the crayons in 3 bags are green are $\frac{3}{12}$
