36 k m divided by h equals 36 cross times 5 over 18 equals 10 m divided by s
72 k m divided by h equals 72 cross times 5 over 18 equals 20 m divided by s
a c c e l e r a t i o n space equals fraction numerator C h a n g e space i n space s p e e d space over denominator T i m e space t a k e n end fraction
a c c e l e r a t i o n equals fraction numerator 20 minus 10 over denominator 20 end fraction equals 0.5 m s to the power of negative 2 end exponent
d i s tan c e space t r a v e l l e d
v squared equals u squared plus 2 a s
20 squared equals 10 squared plus 2 cross times 0.5 cross times s
300 m
