there are 25 trees at equal distances of 5 metres in a line with the well the distance of the well from the nearest tree been 10 m. a Gardner waters all the trees separately starting from the well and he returns to the well after watering each tree to get water for the next find the total distance the gardener will cover in order to water all the trees. it's very urgent please solve it and I will market brain list

Answer 1

First the gardener goes to nearest tree which is 10 meter away then he comes back so the distance he covered is 10+10=20 m

To give water to the second tree he walks 15 m and again comes back 15m so the distance he covered f2fghis time is 15+15=30 m

So this way it will become an a.p.

Now the distance he covered

25/2(2×20+(25-1)×10)

25/2(40+240)

25/2(280)

25×140

3500m

So the gardener walked 3500 m
