Required
Determine the error in the plot
The plot on the attached graph is represented with:
This implies that Raj plotted the x coordinate on the y coordinate and vice versa.
Hence: (c) is true
time= distance/speed
take distance as d. take time as t.
the time taken: d/ 65 for the train however it is the same distance for d/130 so we can say (d/65)-3 = d/130
now solve the equation, multiply both sides by 130
2d-390=d
2d-d=390
so d=390 mi
I think it's 5 with a remainder of 89. Hope this helps! :)
Stars = 1/4
Red stars = 8/9
Multiply:
1/4 × 8/9 = 8/36 = 4/18 = 2/9
Answer = 2/9
Hope this helped☺☺
