Vivek jogs 8 times around a square field of perimeter 140 m How many kilometres and metres
does he jog? He had planned to jog 15 km. How much in metres is still left to jog​

Answer 1

Answer:

79mm , 1km 120m , 13880m

Step-by-step explanation:

1 :- length of line segment = 15cm 4mm = 154mm

     length of remaining segment = 7cm 5mm = 75mm

     length of erased portion = 154mm - 75mm = 79 mm

2 :- distance ran by vivek in 1 round = 140m

     distance ran by vivek in 8 rounds = 140×8 = 1120m = 1km 120m

3:- distance left to jog :- 15km - 1km 120m = 15000m - 1120m = 13880m
