Question

Even though the closest distance from earth to Mars is less than 60,000 Km, the trip ends up being a lot farther since we're both orbiting at different rates on different paths. First, estimate the average speed of Hermes in kilometers per hour IF the actual travel distance was 150 million km and it takes only 124 days.(Round to the nearest thousand kph.) Choose one of the following:

A) 50,000 kph

B) 25,000 kph

C) 5,000 kph

D) 120,000 kph

E) 60,000 kph

F) 100,000 kph

Then, convert that rounded off speed to miles per hour (Rounded to the nearest thousand mph) which is ___________ mph

Lastly, convert that speed in miles per hour to feet per second (Round to the nearest thousand fps) which is ___________ fps.
