<PRE><B>Question 593385</B>
It is approximately 35 million miles from Earth to the planet Mars.
 A spacecraft is launched from Earth heading toward Mars.
 If the spacecraft travels at an average speed of 2,900.meters per second, 
 in about how many days will it take the spacecraft to reach Mars?
:
Change 35 million miles to km
1.609 * 35,000,000 = 56,315,000 km
:
Change 2900 m/sec to 2.9 km/sec
:
{{{56315000/(2.9*3600*24)}}} = 224.75 days</PRE>
