Question

minutes. If the pole be 6 metres high, in what time will it get to the top?
in and the latter 10​

Answer 1

Answer:

ans=8.57 min

Step-by-step explanation:

ATQ

Distance Snail creeps in a min=9(dec)-2(dec)=7 dec

Now there are 10 dec in 1 metre

So the total distance the snail has to travel would be 60 dec

now as we know t=d/s

where we have to find 't' and the speed is 7 dec/min

therefore,60/7=8.57 min
