An automobile traveling 95 km /h overtakes a 1.10-km- long train traveling in the same direction on a track parallel to the road. if the train’s speed is 75 km/h, how long does it take the car to pass it, and how far will the car have traveled in this time? see fig. 2-39. what are the results if the car and train are traveling in opposite directions?

a) 5.5 hours and 412.5 km b) 38 minutes and 47.5 km.

Step-by-step explanation:

Since we have given that

Speed of an automobile = 95 km /hr

Speed of train = 75 km/hr

Length of train = 110 km

If the train and automobile is travelling in the same direction, then the relative speed would be

95-75 = 20 km/hr

So, time taken by the car to pass it would be

Car have traveled in 5.5 hours is given by

Similarly, if they are travelling in opposite directions, then the relative speed would be

So, time taken by the car have traveled this time would be

Car have traveled in 38 minutes is given by

Hence, a) 5.5 hours and 412.5 km b) 38 minutes and 47.5 km.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
