The frequency (f) and length (l) of a wave are related by the following formula: f x l = 3.0 x 1010. consider that the wavelength of x-rays is 1 x 10−11. what is the frequency of x-rays? a)1.1 x 1021b)1.1 x 1024c)3.0 x 1021d)3.0 x 1020

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
