We know that
<span>Monica can walk 3.8 kilometers in 40 minutes
and
</span><span>she can jog twice that distance in the same amount of time
that means
in 40 minutes Monica can jog (3.8 km*2)-----> 7.6 km
1 hour=60 minutes
</span>by proportion<span>
7.6 km/40 minutes=x km/60 minutes
x=7.6*60/40----> x=11.4 km
the answer is
11.4 km</span>

Step-by-step explanation:
The sum of given angles must be equal to 360°
3x° + 2x° + 90° = 360°
5x + 90 = 360
5x = 270 divide both sides by 5
x = 54
