The text you provided contains multiple questions. Here are the answers to each one:

1. To find out how long it will take for the train to pass a platform 650 m long, we first need to find the speed of the train. The speed of the train is distance/time = 240m/24s = 10 m/s. The time it takes to pass the platform is distance/speed = 650m/10m/s = 65 seconds. So, the answer is 65 sec.

2. The relative speed of the two trains is the difference of their speeds, which is 46km/hr - 36km/hr = 10km/hr = 2.78 m/s (since 1 km/hr = 5/18 m/s). The total length of the two trains is the relative speed times the time it takes for the faster train to pass the slower train, which is 2.78 m/s * 36s = 100.08 m. Since the two trains are of equal length, the length of each train is 100.08m/2 = 50.04m. So, the answer is 50 m.

3. The speed of the train is 45 km/hr = 12.5 m/s. The total distance to be covered is the length of the train plus the length of the bridge, which is 360m + 140m = 500m. The time it takes to pass the bridge is distance/speed = 500m/12.5m/s = 40 seconds. So, the answer is 40 sec.

4. The relative speed of the two trains is the sum of their speeds, which is 60km/hr + 90km/hr = 150km/hr = 41.67 m/s. The total length of the two trains is 1.10km + 0.9km = 2km = 2000m. The time it takes for the slower train to cross the faster train is distance/speed = 2000m/41.67m/s = 48 seconds. So, the answer is 48 sec.

5. The relative speed of the jogger and the train is 45km/hr - 9km/hr = 36km/hr = 10 m/s. The total distance to be covered is the distance the jogger is ahead of the train plus the length of the train, which is 240m + 120m = 360m. The time it takes for the train to pass the jogger is distance/speed = 360m/10m/s = 36 seconds. So, the answer is 36 sec.
