Vaimiti walks at a constant pace of 1.1 m/s and takes 25 minutes to get to school.

Temka [501]

Solution:

Note that:

Speed = Distance/Time
Vaimiti speed = 1.1 m/s
Jabril speed = 1.3 m/s

Converting the time (minutes to seconds) for Vaimiti to reach school:

Vaimiti's time to reach school: 25 minutes = 25 x 60 seconds
=> Vaimiti's time to reach school: 1500 seconds

Converting the time (minutes to seconds) for Jabril to reach school:

Jabril's time to reach school: 30 minutes = 30 x 60 seconds
=> Jabril's time to reach school: 1800 seconds

Finding the distance of Vaimiti:

Speed = Distance/Time

Important: The distance will be in meters since the speed units is meters/seconds.

=> 1.1 meters/second = Distance/1500
=> 1.1 x 1500 = Distance
=> 1650 meters = Distance (In meters)

Finding the distance of Jabril:

Speed = Distance/Time

Important: The distance will be in meters since the speed units is meters/seconds.

1.3 meters/second = Distance (In meters)/1800 seconds
=> 1.3 x 1800 = Distance (In meters)
=> 2340 meters = Distance (In meters)

This can lead to two possible solutions:

Possible solution #1:

Finding the difference between the two distances:

2340 meters - 1650 meters = Difference (In meters)
=> 690 meters

Possible solution #2:

The difference between the distances they walked is that Jabril walked faster than Vaimiti, but Vaimiti reached school earlier than Jabril because the walking distance for Vaimiti is less than the walking distance for Jabril.

A swimming pool has a capacity of 2,500 gallons of water. The output of a hose is 25 gallon per minute. How much time would it t

g100num [7]

Answer:

100 minutes

Solution:

We know that:

Capacity = 2,500 gallons
Hose = 25 gallons/minute

Solution:

25 gallons = 1 minute
=> 25x gallons = x minutes = 2500 gallons
=> 25x = 2500
=> x = 100 minutes

Hence, it will take 100 minutes to fill the pool.

How do you factor the common factor out of 30x^2-12x

Anika [276]

The answer would be 6x(5x-2).

Since both terms have x in them, x will be apart of your answer.

The GCF of 12 and 30 is 6.

So you can factor out 6x from both terms.

Hope this helps!
