A cyclist moves around a city which is in the form of rectangle of length 500m and breadth is 300m if the cyclist completes one round of city in 2 hours and 20 minutes then calculate the distance travelled by him in 7 hours |
|
Answer» First find the perimeter of the rectangular plotHenceperimeter=2(l+b)=2(500+300)=2*800=1600mHence one round=1600metre2 hours 20mins=2*60+20=120+20=140minutesHence speed=distance/timespeed=1600/140=11.42m/minHence distance in 7 hours7hours=7*60=420minutesHence distance =speed*time=420*11.42=4796.4metres thanks bro |
