Answer:
she flew 1h 30m and ran 30m
Step-by-step explanation:
First we have to make 2 equations, one that represents the distance that it traveled and another that represents the time that it ran
x = time she ran
y =
time she flew
x + y = 2h
x * 12 + y * 76 = 120
we clear x in the first equation
x + y = 2
x = 2 - y
we replace x with (2 - y) in the second equation
x * 12 + y * 76 = 120
(2 - y) * 12 + y * 76 = 120
24 - 12y + 76y = 120
-12y + 76y = 120 - 24
64y = 96
y = 96/64
y = 3/2
this means that 1 hour and a half was flying
x = 2 - y
x = 2 - 3/2
x = 1/2
this means that half hour was runing

Step-by-step explanation:
To convert from inches to kilometers, we need a conversion factor to relate the two units involved in the problem. <span>We
either multiply or divide this certain value to the original measurement
depending on what is asked. For this case, we use 1 meter is equal to 39.37 inches and 1000 meter is equal to 1 kilometer. We do as follows:
</span><span>3.44 x 108 inches ( 1 meter / 39.37 inches ) ( 1 kilometer / 1000 meter ) = 8737.62 kilometers</span>
You start with 0 then add two pennies (0.02) a day
