Answer:
The distance between them after one hour is 5 km
Step-by-step explanation:
Speed of Somu = 4 km/hr
So, he travels distance in 1 hour = 4 km
Speed of raju= 3 km/hr
So, he travels distance in 1 hour = 3 km
Refer the attached figure
Somu walks towards north at a speed of 4 km per hour
So, distance traveled by Somu in hr = 4 km = AB
Raju walks towards east at a speed of 3 km per hour.
So, distance traveled by Raju in hr = 3 km = AC
So, we are supposed to find BC
So, we will use Pythagoras theorem
So, the distance between them after one hour is 5 km
