Beth and Totsakan left the hospital at the same time. They traveled in opposite directions. Totsakan traveled 10 mph faster than Beth. After six hours they were 300 mi. apart. Find Beth’s speed.

Also this thread is for everyone that needs homework help! I am here to help and to be helped!

Speed equals distance divided by time. So, we have 300 mi./6 hours. That gives 50 mph/ The thing is Totsakan is traveling faster than Beth by 10 mph, so 50 - 10 = 40. Beth’s speed is 40 mph, I think.

basically, you find out their combined speed (like @Katy_2 did) and you divide it by half. so 50/2=25.
since the difference between the two speeds are 10mph, divide that by half as well so you get 5mph.
then subtract 5 from 25, and add 5 to 25, you’ll get 20 and 30mph.
to check the answer, 20x6=120 while 30x6=180 which adds together to equal 300!

I know in what book to find it but it doesn’t want to be found @nicollil how much time do you have to solve it ?
( For me it’s night and I want to sleep sorry)

Lisa and Mei left home at the same time. They drove in opposite directions. Mei
drove 18 mph faster than Lisa. After one hour they were 138 mi. apart. Find Lisa’s
speed.

The answer for this is 60. So, Lisa’s speed is 60 mph, and then Mei’s speed is 78 mph.

I just don’t know how to solve this. I’m wondering if you have to divide the distance by half or something.
