A speed skating track has a perimeter of 400m. Determine the straightaway length of the track.
* the width of the track is 50m*
Please help . Thank you for your time
by width, I assume you mean the distance between the parallel straight sides. If so, then the track consists of two straightaways of length L, and a complete circle of diameter 50. So,
2L + 50π = 400
2L+2W = 400.
2L + 2*50 = 400
L =
To determine the straightaway length of the track, we need to subtract the width of the track from the perimeter.
Given that the perimeter of the track is 400m and the width of the track is 50m, we can calculate the straightaway length as follows:
Straightaway length = Perimeter - (2 × Width)
Since there are two straightaways in a track, we need to subtract the width twice.
Straightaway length = 400m - (2 × 50m)
Now, let's calculate the straightaway length:
Straightaway length = 400m - 100m
Straightaway length = 300m
Therefore, the straightaway length of the track is 300 meters.
