Sputnik was actually the first artificial Earth satellite launched by the Soviet Union in 1957. It did not travel to Mars, but instead orbited Earth. It took the spacecraft about 98 minutes to orbit the Earth.
it would take at least 197.456 hours to get to mars from earth
Sputnik 1, the first artificial satellite, took approximately 96.2 minutes to orbit the Earth once.
About 250 days, but I haven't checked the exact number. (I guess you mean the Mars Exploration Rover mission.)

Sputnik 1 took approximately 96.2 minutes to orbit the Earth once.
About an hour and a half.
NASA did not build Sputnik. Sputnik was a Russian satellite, not an American one.The Soviets have not released any information about how long it took to design and build the satellite.
Using current technology: it can take as little as 6 months and as long as a year to get to mars at optimum position
