Answer:
24
Step-by-step explanation:
Answer:
(6x+3) (4x-5) = 24x^2 -30x +12x -15 = 24x^2 -18x -15
I get the same answer. I guess we're both wrong?
Or do they want it reduced to:
8x^2 -6x -5
Step-by-step explanation:
The train will pass the jogger in 36 seconds.
Length of train = 120m
Speed of train = 45kmph
Distance by which the jogger is ahead of the engine of the train = 240 m
Speed of jogger = 9 kmph
To pass the jogger, the train will have to cover the length of the train and the distance by which the jogger is ahead of the engine of train.
Hence,
Distance = 120 + 240 = 360m
As,
Time = Distance/Speed
Relative speed of train w.r.t jogger = 45 - 9 = 36 kmph = 10 m/s
Hence,
Time = 360/10 = 36 seconds.
