Verified answer

Answer:

Total distance traveled is 3500m

Step-by-step explanation:

The distance of nearest tree is 10m

so that distance travelled to water nearest tree =20m ....... (10×2=20m)

The distance of next nearest tree is 10+5=15m

so total distance travelled =15×2=30m

following form an A.P of terms : - (20,30,40,50.........)

∴ We have to find total distance travelled,

∴ we have to find S

25

n=25,a=20d=10

∴S

n

=

2

n

(2a+(n−1)d)→ formula

∴S

25

=

2

25

(2×20+(25−1)10)

∴S

25

=

2

25

(40+24×10)

∴S

25

=25(20+120)

∴S

25

=25×140

∴S

25

=3500m

Total distance traveled is 3500m

Step-by-step explanation:

the total distance travelled is 3500m
