If Car A is going 70 miles an hour and Car B is 1/2 mile behind Car A how fast would Car B have to go in order to catch Car A within a 2 mile radius!!!
\n" ); document.write( ":
\n" ); document.write( "Let s = the required speed of car B
\n" ); document.write( "We can say that Car B has to travel 2.5 mi while Car A travels 2 mi
\n" ); document.write( "Distance and speed vary directly
\n" ); document.write( "\"s%2F70\" = \"2.5%2F2\"
\n" ); document.write( "cross multiply
\n" ); document.write( "2s = 70 * 2.5
\n" ); document.write( "2s = 175
\n" ); document.write( "s = 175/2
\n" ); document.write( "s = 87.5 mph for Car B to catch Car A with in a 2 mi radius
\n" ); document.write( ":
