Answer:
Train B is going faster
Step-by-step explanation:
The distance Train A travels is represented by [tex]d=70t[/tex]
where d is the distance in kilometers and t is the time in hours
The speed of train A is 70 kilometer per hour
To find speed of train B use the table
find out slope
[tex]\frac{y_2-y_1}{x_2-x_1} =\frac{300-150}{4-2} =75[/tex]
The speed of train B is 75 km per hour
The speed of the train B is more
Train B is going faster
Answer:
Unit rate of Train A is [tex]70km/hr.[/tex]
Unit rate of Train B is [tex]75km/hr.[/tex]
Train B is going faster.
Step-by-step explanation:
Given information
The distance Train A travels is represented by
[tex]d=70t[/tex]
Now, to find unit rate of Train A
Consider, [tex]t=1[/tex]
So, unit rate of Train A
[tex]= 70*1\\=70 km/hr.\\[/tex]
Similarly , according to the given table the distance traveled by Train B in 2 hour that means from 2 to 4 is:
[tex]=300-150\\=150[/tex]
So, the unit rate of Train B will be
[tex]=150/2\\\\=75 km/hr.[/tex]
That means Train B travels 75 [tex]km.[/tex] in 1 hour, which is higher than the unit rate of Train A.
So, Train B is going faster.
