# Can anyone help me with Dimensional Analysis? (Math/Science)?

Is anyone good at dimensional analysis? it is just converting things into another.. well, i'm done with the first 20 problems, but the last 3 are really confusing to me. can anyone help me and show work while they are at it? >.<

1. A typical car manufactured in 1974 weighs 4000 pounds. How many McDonald's Quarter Pounders is this? If the Quarter pounder costs \$0.65 in 1974 and the car costs \$6,000, then which is cheaper, the car of the car's weight in Quarter Pounders?

2. What is the speed of a car in feet/second that is traveling at 60 miles/hour? <--we havent learned about how to convert this yet.. so i'm confused about it, otherwise i think it would be pretty simple for me..

3. The space shuttle travels at 28,000 mph while orbiting the Earth. How far does the shuttle travel in feet in the blink of an eye?

Blink of an eye= 1/10 of a second

Thank you whoever helps me!! Please do show work!
