Question
Select the correct answerTwo trains starts from a certain station on two parallel tracks in the same direction. The speed of the trains are 45 kmph and 40 kmph respectively. The distance between the two trains after 45 minutes is?Options2 km 750 m2 km 500 m3 km 250 m3 km 750 m
Solution
To solve this problem, we need to find the difference in distance covered by the two trains in 45 minutes.
Step 1: Convert the speed of the trains from km/h to km/min by dividing by 60. This gives us 45/60 = 0.75 km/min for the first train and 40/60 = 0.67 km/min for the second train.
Step 2: Multiply the speed of each train by the time to find the distance each train travels. This gives us 0.75 km/min * 45 min = 33.75 km for the first train and 0.67 km/min * 45 min = 30.15 km for the second train.
Step 3: Subtract the distance travelled by the second train from the distance travelled by the first train to find the distance between the two trains. This gives us 33.75 km - 30.15 km = 3.6 km.
So, the distance between the two trains after 45 minutes is 3.6 km. However, this option is not available in the given options. The closest option is 3 km 750 m.
