a car travels 1480 km in 13hr 24 min.
\n" ); document.write( "if car covers 3/5 of the journey at a speed of 148 km/hr,
\n" ); document.write( "find the speed of the car for the rest of the journey?
\n" ); document.write( ":
\n" ); document.write( "Change 13 hr 24 min to hrs: 13 + $\"24%2F60\"$ = 13.4 hrs
\n" ); document.write( ":
\n" ); document.write( "Find the distance traveled at 148 km/hr
\n" ); document.write( " $\"3%2F5\"$ * 1480 = 888 km
\n" ); document.write( "then
\n" ); document.write( "1480 - 888 = 592 km at an unknown speed (s)
\n" ); document.write( ":
\n" ); document.write( "Write a time equation; time = dist/speed
\n" ); document.write( " $\"888%2F148\"$ + $\"592%2Fs\"$ = 13.4
\n" ); document.write( "6 + $\"592%2Fs\"$ = 13.4
\n" ); document.write( " $\"592%2Fs\"$ = 13.4 - 6
\n" ); document.write( " $\"592%2Fs\"$ = 7.4
\n" ); document.write( "s = $\"592%2F7.4\"$
\n" ); document.write( "s = 80 km/hr on the rest of the journey
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You can check this out find the time at each speed, should total 13.4 hrs\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
