70 miles in 3 hours, so speed is 70/3 miles/hour
\n" ); document.write( "Since 35% of his trip takes 3 hours
\n" ); document.write( " $\"35%2F100+=+3%2Fx\"$ where x is the number of hours for the whole trip
\n" ); document.write( "so 35x = 3*100
\n" ); document.write( "35x = 300
\n" ); document.write( "x = 300/35 hours
\n" ); document.write( "rate * time = distance
\n" ); document.write( "(70/3)*(300/35) = 200 total distance to travel
\n" ); document.write( "Since the traveler has traveled 70 miles so far,
\n" ); document.write( "there are (200-70) = 130 miles to go
\n" ); document.write( " $\"70%2F3+hours+=+130%2Fx\"$ where x is the time to complete the trip
\n" ); document.write( "70x = 3*130
\n" ); document.write( "70x = 390
\n" ); document.write( "x = 390/70 = 5.5714 hours to go\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
