If two girls are walking to school. One is 1250 meters from school and traveling at 70meters per minute and the other girl is 850 meters from school and travels at 40 meters per minute and they leave at the same time when if ever will they meet?

Solution

You didn\'t tell us their route to school! They might meet at school and then again maybe not. We don\'t even know if they go to the same school.
a\'s
1250=70x
125/7=17.8571 minutes
b\'s
850=40x
85/4=21.25 minutes
70x=40x+400
x=13 minutes 20 seconds they meet.
