Please help me to solve this \r
\n" ); document.write( "\n" ); document.write( "problem #1
\n" ); document.write( "Two cars leave a town and travel in opposite directions. One car travel at the rate of 45 pkh and the other at 55 kph. In how many hours will the two cars be 350 kilometers apart?
\n" ); document.write( "one car speed = 45 kph
\n" ); document.write( "other car speed = 55kph
\n" ); document.write( "effective speed will be 55+45 = 100 kph since they are moving away from each other.
\n" ); document.write( "Distance = 350 km
\n" ); document.write( "time = distance / speed
\n" ); document.write( "350/100
\n" ); document.write( "= 3.5 hours\r
\n" ); document.write( "\n" ); document.write( "Problem #2
\n" ); document.write( "How long will it takes a bus traveling at 60 kph to overtake a car traveling at 40 kph if the car had a 1.5-hour head start?\r
\n" ); document.write( "\n" ); document.write( "Bus speed = 60 kph
\n" ); document.write( "car speed = 40 kph
\n" ); document.write( "effective speed = 20kph . Bus will catch up 20 kph
\n" ); document.write( "car has left 1.5 hours early. so in 1.5 hours it travels 60 km
\n" ); document.write( "Time = distance/speed = 60/20 = 3 hours bus will catch up.
