A scale model of a bicycle has a scale of 1:30. The
reau bicyde has a length
of 1.5m. What is the length
of the model in cm.

5cm

Step-by-step explanation:

Convert 1.5m into cm to make it easier to solve.

1.5m --> 150cm (*100)

The real bike length is 30 times larger than the scale. So to undo this we need to divide by 30.

150cm / 30 = 5cm

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

5104.38 inches
