The speed of a space shuttle is 3.2×10^6 cm/s. Convert this into miles per hour (mph) using only 12 inches/ft, 60 seconds/min, 60 minutes/hour, and 1 inch = 2.54 cm. Factor Analysis must be used. Express your result to three significant digits and in scientific notation.

Answer 1

speed=3.2E6cm/s*(1in/2.54cm)*(1ft/12in)(1mile/5280ft)(60sec/min)(60min/hr)

Sorry, had to use a conversion from 5280ft/mile.

Answer 2

I got 71.6*10^4?

Answer 3

put this into your google search window;
3.2E6*(1/(2.54*12*5280))*60*60=

I think you are off some.
