Alan leaves Los Angeles at 8:00 a.m. to drive to San Francisco, 380mi away. He travels at a steady 45.0mph. Beth leaves Los Angeles at 9:00 a.m. and drives a steady 57.0mph.(adsbygoogle = window.adsbygoogle || []).push({});

they want to know how long does the first to arrive have to wait for the second?

I know the method to go about solving this problem ( i think) but it is unusable unless i were to know how far beth is from san fran. this looks to me like an equation that i dont know, but im thinking something algebraic to solve for the missing distance.

for alan i said that 380mi/45mph would equal 8 hrs and 20 mins. beth, i dont know
