1 in 13 or 1/13 because those are the only numbers it gives you and since he only sold one vanilla cone in the last thirteen cones you can only assume that he sells one vanilla every 13
Let the boat speed in still water be b.
Let the current speed be c.
The speed going upstream is 20/4 = 5 mph.
The speed going downstream is 32/4 = 8 mph.
b - c = 5 ........(1)
b + c = 8 .......(2)
Adding equations (1) and (2) we get:
2b = 13
b = 13/2 = 6.5
Plugging in the value for b into equation (1) we find c = 1.5.
The boat speed in still water is 6.5 mph and the current speed is 1.5 mph.
2400 divided by 10 is 240 and 240 x 3 = 720 so your answer would be 720 calories per day
