Firstly we calculate.... Perimeter of rectangle = 2(l+b)
= 2(80+35)
= 230m
He take around the field 3 times means =
3*230
= 690m
He walk 1.5 per second means he walk 1 meter in 1.5 second.....
so, He take time for around the field 3 times
= 690/1.5
= 460 second
= 2(80+35)
= 230m
He take around the field 3 times means =
3*230
= 690m
He walk 1.5 per second means he walk 1 meter in 1.5 second.....
so, He take time for around the field 3 times
= 690/1.5
= 460 second
