Answer 3

I think its a pattern..

mph ---- cal
2 ------ 110
3 ------ 180
4 ------ 260
5 ------ ?

180 - 110 = 70 (difference of 70)....so 70 was added to find the next calorie number
260 - 180 = 80 (difference of 80)...so 80 was added to find the next calorie number
so the next number...5 mph.....add 90 to 260
