Hi I have to solve this conversion for Chemistry class,this is the only one I cannot solve. I have to set it up with scientific notation and so they cross out. I have the answer I just do not know how to set it up.
The speed of a car is 43.5 mph. What is its speed in units of km/s (1km=0.6214 mi)
Correct answer should be 1.94x10^-2km/s/
Thank you so much.

43.5 miles = 43.5mi x 1km/0.6214mi = 70.0km
1 hour = 60 x 60 seconds = 3600s
so 70.0km/3600s = 0.0194km/s or 1.94x10^-2 km/s
1 hour = 60 x 60 seconds = 3600s
so 70.0km/3600s = 0.0194km/s or 1.94x10^-2 km/s
