Shawn is coasting down a 500 \text{ cm}500 cm500, start text, space, c, m, end text long ramp on his inline skates. The wheels on his inline skates are 32\text{ cm}32 cm32, start text, space, c, m, end text in circumference.
How many rotations does each wheel make while Shawn is coasting down the ramp?

Step-by-step explanation:

the comments say so

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
