Total time= 8 hours
Time to go to the spot = 4 hours
Time to return = 4 hours
Average speed while going = 40 mph
Average speed while returning = 30 mph
Therefore
max distance while going = 4 × 40 m
= 160 m
max distance while returning =4 ×30 m
= 120 m
Therefore
max distance he can select a picnic spot will be the least distance between max distance while going and coming
i.e., 120 m
Ans:- 120m
