reversed no. is 10u+t
so its (10u+t)-(10t+u)=18
which gives 9u-9t=18

After 2 hours time , both Abe and Gabe to cost the same amount .
<u>Step-by-step explanation:</u>

Let the time for which both Abe and Gabe to cost the same amount be x hours, so according to question scenario we will have equation as :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , After 2 hours time , both Abe and Gabe to cost the same amount .
