The speed limit on some interstate highways is roughly 100 km/h. (a) what is this in meters per second? (b) how many miles per hour is this?

Explanation:

given,

speed limit on the highway is roughly  = 100 km/hr

a) to calculate limit in meter per second          

   1 km/h =

   100 km/h =

                    = 27.78 m/s            

b) to calculate limit in meter per second

   1 km = 0.6213 mile          

  100 km/hr = 100 × 0.6213 mi/hr

                    = 62.13 mi/hr              

show the diagram then i will answer
