Jan and jo live 1,170 miles apart. at the same time, they start driving toward each other on the same road. jo’s constant rate is 60 mph. jan’s is 70 mph. how long will it take them to meet?

To get the time taken for Jan and Jo to meet we proceed as follows;
Jan's speed=70 mph
Jo's speed =60 mph
distance between =1170
relative speed=70+60=130
time taken for them to meet will be:
time=(distance)/(relative speed)
=1170/130
=9 hours
the answer is 9 hours

Something that is true about that is that it has numbers
