Sir he was 6km from the starting point means from the point he started to walk.. 3km us ny walk py lgaye to 6km main sy 3km minus ni krain gy? Kyun k poocha to bs running ka e hy na

[@StudyRiver]

He walked for 45 minutes at 3 km/h and from here we can calculate the distance covered through walking that comes to 3 x 0.75 hrs = 2.25 km (45 minutes equal to 0.75 hr) Now the remaining disatance is 6 - 2.25 km = 3.75km. it was covered in half hour. now we calculate speed. 3.75/0.5 hr = 7km /hr In both cases answer is same
