20points ASAP!! close to grade 5 Towns P, Q, R and S are shown.
Q is 35 kilometres due east of P.
S is 15 kilometres due west of P.
R is 15 kilometres due south of P.

a) Work out the bearing of R from S?

b) Work out the bearing of R from Q?

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
