Question

The puppy needs to catch a train that is moving at 8 km/h. She is 100m away and running at 10 km/h. How far will the train have traveled before the puppy is able to jump on?​

Answer 1

400 meters

0 meters if the puppy can jump really really far ha ha ....

P = 10000x - 100

T = 8000x

10000x - 100 = 8000x

2000x = 100

x = 1/20 hr

60/20 = 3 minutes
