A train 380 m long moves at 70 km/h. How long does it take to pass a platform of length 290 m?
Answer:
34.46
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 70 * (1000/3600) = 19.44 m/s. 3. Time = Distance / Speed = (380 + 290) / 19.44 = 34.46 s.
92
A train 460 m long moves at 91 km/h. How long does it take to pass a platform of length 251 m?
Answer:
28.13
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 91 * (1000/3600) = 25.28 m/s. 3. Time = Distance / Speed = (460 + 251) / 25.28 = 28.13 s.
93
A train 300 m long moves at 91 km/h. How long does it take to pass a platform of length 271 m?
Answer:
22.59
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 91 * (1000/3600) = 25.28 m/s. 3. Time = Distance / Speed = (300 + 271) / 25.28 = 22.59 s.
94
A train 180 m long moves at 61 km/h. How long does it take to pass a platform of length 241 m?
Answer:
24.85
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 61 * (1000/3600) = 16.94 m/s. 3. Time = Distance / Speed = (180 + 241) / 16.94 = 24.85 s.
95
A train 200 m long moves at 67 km/h. How long does it take to pass a platform of length 247 m?
Answer:
24.02
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 67 * (1000/3600) = 18.61 m/s. 3. Time = Distance / Speed = (200 + 247) / 18.61 = 24.02 s.
96
A train 540 m long moves at 70 km/h. How long does it take to pass a platform of length 270 m?
Answer:
41.66
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 70 * (1000/3600) = 19.44 m/s. 3. Time = Distance / Speed = (540 + 270) / 19.44 = 41.66 s.
97
A train 540 m long moves at 73 km/h. How long does it take to pass a platform of length 273 m?
Answer:
40.09
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 73 * (1000/3600) = 20.28 m/s. 3. Time = Distance / Speed = (540 + 273) / 20.28 = 40.09 s.
98
A train 440 m long moves at 85 km/h. How long does it take to pass a platform of length 245 m?
Answer:
29.01
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 85 * (1000/3600) = 23.61 m/s. 3. Time = Distance / Speed = (440 + 245) / 23.61 = 29.01 s.
99
A train 440 m long moves at 86 km/h. How long does it take to pass a platform of length 246 m?
Answer:
28.72
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 86 * (1000/3600) = 23.89 m/s. 3. Time = Distance / Speed = (440 + 246) / 23.89 = 28.72 s.

A train 500 m long moves at 60 km/h. How long does it take to pass a platform of length 260 m?
Answer:
45.6
Step-by-step solution: 1. Relative distance to cover = train length + platform length. 2. Convert speed to m/s: 60 * (1000/3600) = 16.67 m/s. 3. Time = Distance / Speed = (500 + 260) / 16.67 = 45.6 s.
