Okay, so
a=2b+11
<span>a+b = 2(a-b) </span>
<span>now solve </span>
<span>a+b = 2a-2b </span>
<span>3b = a, put that into the 1st equation: </span>
<span>3b = 2b+11 </span>
<span>b=11 </span>
<span>a = 2(11) +11 = 33 </span>
<span>check in the 2nd equation: </span>
<span>33+11 = 2(33-11) </span>
<span>44 = 2(22) </span>
<span>44 = 44</span>

Jimmy is trying to escape Jane
For finding total distance , we will find distances and then add them
He runs 12 km/hr for 5 minutes
First distance:
speed =12 kh/hr
time=5 minutes
we can change into hour


now, we can plug values


second distance:
speed =17 kh/hr
time=8 minutes
we can change into hour


now, we can plug values


third distance:
speed =6 kh/hr
time=2 minutes
we can change into hour


now, we can plug values


now, we can find total distance



so,
total distance is 3.46667 km...........Answer
