A school administrator tells everyone in the building that they will be having a fire drill randomly sometime during the school day which is from 8 a. m. to 3 p. m. If second period is from 9:20 a. m. to 10:10 a. m., what is the probability of the fire drill happening during second period?

Hope i can you!

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.

Using the rise/run rule. you would get 2/6.simp. 1/3
