the 2002 denali earthquake in alaska had a richter scale magnitude of 6.7. the 2003 rat islands earthquake in alaska had a richter scale magnitude of 7.8.
(show work)

answer: my frend told me heres the answer

the building strong enough to withstand the denali   quakestep-by-step explanation:

denali quake 6.7   x 70 = 469

the building in denali should be strong enough to withstand an earthquake of that magnitude  

rat island quake 7.8 x 30 = 234

the building in the rat islands   should be strong enough to withstand an earthquake of that magnitude  

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
