Question

Two cars leave towns 800 kilometers apart at the same time and travel toward each other. One cars rate is 16 kilometers per hour less than the others. If they meet in 4 hours what is the rate of the slower car

Answer 1

let the speed of one car=x kms/hr
speed of other car=x-16 kms/hr
time t=4 hrs.
\[x \times4+(x-16)\times4=800\]
divide by 4
x+x-16=200
x=?
x-16=?
