document.write( "Bus station is 10km away. To catch bus before it leaves, you must travel a rate of 60km/hr by car to get there. There is bad weather so you're only able to drive 30km/hr for the first 5km. What speed must you travel the rest of way to catch the bus?
\n" );
document.write( "What I'm thinking so far...
\n" );
document.write( "If you should drive 60km/hr, then 1km should take 1 min (60 divided by 60). Therefore it should normally take 10mins to get there.
\n" );
document.write( "30km/hr divided by 60 would mean you traveled 0.5km/min. So 0.5 x 10= 5km for 10mins. Now what? \n" );
