Karen drives his car 96 miles in 1.5 hours. if he continues to drive at this rate, how far will he travel in 2.5 hours?

96/1.5 would be your unit rate which is 64 then multiply your unit rate times 2 and you get  128 miles.

If you do 96+96 you get 192 so then you divide that number by 3 which gives you 64 which is the rate per hour. then you do 64+64 or 64 by 2 which will give you 128 and then you add half of 64 which will give you 32 so the answer is 160
