Asked by Mr me

After visiting your Nana for christmas, your brother and you drive off in opposite directions. Your brother takes the highway and travels twice the speed than your average speed through various cities. After 2 hours, you both arrive at your homes. If you live 258 miles away from your brother, approximately how fast are you both driving
Answered by Steve
since distance = speed * time, if your speed is x, then

2*x + 2*2x = 258
