Which one of the given compounds is consistent with the mass spectrum below? SDBS: National Institute of Advanced Industrial Science and Technology CH3CH2CH(CH3)2 CH3CHOHCH2CH3 CH3CH2OCH2CH3 CH3CH2NHCH2CH3 CH3CH2CH2CH3

its b it was a compound

answer;

18.5 seconds

explanation;

velocity is distance covered per unit time; it is given by displacement divided by time.

thus; time = displacement/velocity

total time = total displacement/velocity

total distance = 5000 meters south

total time = 5000/4.5

                  = 1111.11 seconds

but; 1 minute = 60 sec

thus; 1111.11 /60

                = 18.51 seconds

thus; the time taken is 18.5 seconds
