- 20 minutes
person climbs 12 m in a minute & slips down 8 m
so,he goes up 12-8 = 4 m up in a minute
thus, in 19 minutes, he will be 19*4= 76 m up
on 20 th minute he will be at top of the pole i.e at 76+12 = 88 m & willn't slip down. - 10 years agoHelpfull: Yes(3) No(0)
- in every min person climbs up 12m and slips 8m . hence net displacement becomes 4m.
in 19 minutes person would climb (19*4)=76m
in 20th minute person would climb 12m up.. and it will be on top.
hence in 20th minute. person will reach on pole. - 10 years agoHelpfull: Yes(2) No(0)
- it should be 39min
2min=12-8=4meter
?min=88-12=76
(2*76)/4=38 min
at 38 min it should be on 76 meter
at 39 min 76+12=88meter - 7 years agoHelpfull: Yes(0) No(1)
- 88/4
so 22 min to reach the top - 7 years agoHelpfull: Yes(0) No(1)
