After how many hours (approx) wil she able to reach ranga ?
Note : she uses same strategy (45 min + 15 min rest) ,ignore time spent at top most point of gate, shifting time
PARAGRAPH :
King kai is training goku and his fellow saiyans to help them reach the level of super saiyans. For this he orderered goku to run on his planet on a track along the equator. The only source of energy for the saiyans are the senzu beans, which are available only at king kais house (the starting point of the track) The total number of beans available is 125. Each saiyan can carry a maximum of 20 beans at any point of time. However, 20 beans would take a saiyan only half the total distance. So king kai allowed goku to take the help of other saiyans, but with a caveat-the saiyans(including goku) can complete the task by utilizing only the minimum number of senzu beans needed
Note: If a senzu bean is broken , it will loose its power
The saiyans who help goku :
-can help each other as well - can run in the reverse direction also
-can return any number of times to king kais house for the beans
- should return to king kais house
– they cant stay on the track somewhere because of lack of senzu beans
1) Find out the minimum number of Senzu beans needed by the Saiyans (including Goku)
2) Also find out the minimum number of Saiyans whose help Goku would need in completing his task
