Not usually. Given numbers a and b, the mean or average is (a + b)/2 but the geometric mean is sq rt (a X b). If both a and b equal 1, the results are the same.
√a / √b = √(a/b)
What ever B is. 2B is 2 times that
it means that A and B have the same power
Bed&Breakfast, usually
No, a 40t is bigger. 40t vs 20t refers to the number of teeth(that engages with the chain) that each wheel has at its circumference. The tooth size is fixed for all bikes that use the same chain spacing, so a 40t chainwheel will have double the circumference of a 20t wheel.
92
10t
-40t
13t front 40t rear
14t on front. 40t on back
That factors to 4t(2t + 1)(5t - 6)
When B is given a 40metre start then B runs 960m in T secs and A runs 1000m in T-19 secs. When B is given a 30 second start then B runs 1000m in t secs and A runs 960m in t - 30 secs. Assume that the speed of A (Va) and B (Vb) is constant in both situations. Then Vb = 960 ÷ T = 1000 ÷ t, and Va = 1000 ÷ (T - 19) = 960 ÷ (t - 30) So 960t = 1000T, and 1000t - 30000 = 960T - 18240. Then 40t = -40T + 11760, t = -T + 294. Substituting for t in 960t = 1000T gives : -960T + 282240 = 1000T : 1960T = 282240 : T = 144 B 's speed is 960 ÷ T = 960 ÷ 144 = 6.67 metres per second. Assuming the same constant speed to run 5000 metres then the time taken is 5000 ÷ 6.67 = 750 seconds

If you mean: 7b+b+b then it is 9b simplified
