Answer:

Distance covered by person with speed 9 km/hr is 9km.

Step-by-step explanation:

Given a person cover 15 km distance in 3 hr. He travel some distance with the speed of 3 km/h and rest of distance with speed 9 km/hr. we have to find the distance with speed 9 km/hr.

Let x be the distance covered with speed 3 km/hr

∴ (15-x) distance covered with the speed of 9 km/hr

Total time to cover 15 km distance=3 hr

⇒ x=6

Hence, distance covered by person with speed 9 km/hr is

15-x=15-6=9 km
