X<-5 and x>2 is the solution to the two inequalities
Hello! So, the train travels 80 miles in an hour. 90 minutes is equivalent ot 1 ½ hours. In case you don't know, ½ of 80 is 40. To find the distance gone in 90 minutes, we can just add 80 and 40. 80 + 40 is 120. Another way to solve it is to multiply 80 by 1.5 and you would still get the same answer. There. The train will have gone 120 miles in 90 minutes.
The answer is $17.55.
Explanation:
All you have to do to find the answer is add $13.05 and $9.40 to get $22.45. Then, it says he paid with two $20 bills, which is $40. So after that, all you do is subtract $40-$22.45.
Hope this helps :)
