Answer:
VIRGO!!!!! <3333
Step-by-step explanation:
Meet in 2 hours
means that the distance covered over 2 hours adds to total distance which is 13miles
basically, imagine instead of moving in oposite directions, toward each other, imagine that one moves for 2 hours then theh other one moves for another 2 hours, total 13 miles
so
speed1=x
speed2=y
x is 2.1 more than y
x=2.1+y
distance=speed times time
time=2hours
speed=x and y
total distance=13
13=2x+2y
x=2.1+y
sub
13=2(2.1+y)+2y
13=4.2+2y+2y
13=4.2+4y
minus 4.2 from both sides
8.8=4y
divide both sides by 4
2.2=y
sub
x=2.1+y
x=2.1+2.2
x=4.3
the hikers hiked 2.2mph and 4.3mph
