In order to assess which method of transportation is faster, we will look at the time they take, since the distance is the same for both. In order to compare the times, we must make the units that they are both measured in consistent. We must either convert 18.5 minutes into hour or 0.5 hour into minutes. We will go with the latter as it is easier:
0.5 hours = 0.5 hours x 60 minutes per hour = 30 minutes
Therefore, the public transport takes them to the mall faster, since it takes only 18.5 minutes, than cycling to the mall does, which takes 30 minutes.
Answer:
x = 41
Step-by-step explanation:
We know these angles will be equal to each other (they are across from each other, I honestly forget the term ) so we can set up an equation
Our equation from given: 104 = 3x - 19
Adding 19 to both sides 123 = 3x
Dividing both sides by 3: 41 = x
Answer: x = 41
Answer:
the mass of the empty box is 4/3 kg.
Step-by-step explanation:
The total mass (box plus 4 books and 2 files) is 2 kg
When half of the load is removed (2 books and 2 files) the mass is 1 3/20.
We have the following equation:
2 kg - (x/2)= 1 3/20 kg
Where x is the total mass of the load (4 books and 2 files)
This steps where followed to solve the equation:
2 -x/2 = (20-3)/20
40-10x=17
23=10x
x=2/3 kg
That is the total mass of the load
Hence
2kg -2/3 kg= 4/3 kg, the mass of the box
