Ruth and tom have the same point driving in opposite directions. Traffic conditions enable Tom to average 10 km/hr more than Ruth. After two hours, they are 308 km apart. Find the speed (Rate) of each person.
Answered by Reiny
Ruth's speed --- x km/h
Tom's speed --- x+10 km/h

in two hour:
Ruth went 2x km
Tom went 2(x+10) km

solve for x

2x + 2(x+10) = 308
