Answer:
0.3
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.

Y + 5 = 1(x - 1)
y + 5 = x - 1
y = x - 6 is the answer
Answer:
15
Step-by-step explanation:
First, you find out how much Allen rode his bike. You can find the answer by doing 45 x 6 for the days he worked out. The answer you get is 270.
Secondly, you must subtract 270 from 360 for the minutes he worked out last week which equals 90.
Finally, you divide 90 by 6 which makes 15.
15 minutes per day.
