Question

a rectangular park, 100m by 80m, at the rate of 9 km per hour. how time will he take in jogging 6 round?the minimum and maximum distance between the two points on ellipse are​

Answer 1

Step-by-step explanation:

perimeter of park=2(1+b)=2(100+80)=2*180=360 m

perimeter of park=2(1+b)=2(100+80)=2*180=360 mdistance of 1 round =360 metres

perimeter of park=2(1+b)=2(100+80)=2*180=360 mdistance of 1 round =360 metresdistance of 6 rounds=360*6=2160 metres

perimeter of park=2(1+b)=2(100+80)=2*180=360 mdistance of 1 round =360 metresdistance of 6 rounds=360*6=2160 metresspeed of mridul=9kmph

=9*1000/3600=2.5 m/s

=9*1000/3600=2.5 m/sSpeed =distance/time

=9*1000/3600=2.5 m/sSpeed =distance/timetime=dist./speed

=2160/2.5

=865 sec

=14 min 25 sec
