<h2>Answer:</h2>

The time taken by them to be 54 miles apart is: 4.5 hours

<h2>Step-by-step explanation:</h2>

Let it takes t hours for both the boats such that they are 54 miles apart.

The northbound boat travels 4 miles per hour.

Hence, the distance traveled by the northbound boat is: 4t miles.

( since the distance is the product of speed and time.

i.e.

Distance=Speed×Time)

The speed of the southbound boat is: 8 miles per hour.

This means that the distance traveled by this boat in t hours is: 8t miles

Hence, the total distance between the two boat in t hours is:

4t+8t=54

i.e.

12t=54

i.e.

t=54/12

i.e.

t=4.5 hours

                    Hence, the answer is: 4.5 hours

£54,000 split ratio 1:3:8
Scrat [10]
There are 12 parts to the ratio (1 + 3 + 8 = 12).
Divide 54,000 by 12.
54,000/12 = 4,500
Now multiply for each part:
1 = 4,500
3 = 13,500
8 = 36,000

You can check by adding them up (4,500 + 13,500 + 36,000 = 54,000).

So the ratio is 4,500:13,000:36,000

Hope this helps =)

Answer:

Number of  jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)

Step-by-step explanation:

Given:

Amount of salt containing in jar = 32 gram

Total amount of salt in jar = 15 kg

Find:

Number of  jars can be filled from 15kg of the salt

Computation:

Total amount of salt in jar = 15 kg

Total amount of salt in jar (in grams) = 15 x 1000 g

Total amount of salt in jar (in grams) = 15,000 g

Number of  jars can be filled from 15kg of the salt = Total amount of salt in jar (in grams) / Amount of salt containing in jar

Number of  jars can be filled from 15kg of the salt = 15,000 / 32

Number of  jars can be filled from 15kg of the salt = 468.75

Number of  jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)
