Answer:
Speed of one dog is 2.5 m/s and other dog is 5.5 m/s.
Step-by-step explanation:
Total distance between the two dogs = 360 m
Let the speed of one dog be x m/s, then the speed of second dog will be x+3 m/s.
Then total speed of two dogs = x+x+3 = 2x+3
Times = 20 seconds
After 20 seconds, distance left between them = 200 m
Distance traveled by the two dogs in 20 seconds = 360 m - 200 m
= 160 m
We know, Speed =
2x+3 =
2x = 8-3 = 5
x = 2.5 m/s
Speed of first dog = 2.5 m/s
Speed of second dog = x+3 = 2.5 +3
= 5.5m/s
Speed of one dog is 2.5 m/s and other dog is 5.5 m/s.
