Being 250 meters apart, two puppies started running towards each other at the same time. the first puppy ran 1.5 meter per second, while the second one ran 2.5 meters per second. what was the distance between them in half a minute?

130 meters

Step-by-step explanation:

Puppy 1

d=rt

We know the rate = 1.5 m/s  and the time = 1/2 minute = 30 seconds

d = 1.5 * 30 = 45 meters

Puppy 2

d=rt

We know the rate = 2.5 m/s  and the time = 1/2 minute = 30 seconds

d = 2.5 * 30 = 75 meters

The puppies ran a total of 75+45 = 120 meters

The total distance was 250

250-120 = 130

There was still a gap of 130 meters between the puppies.
