3distance questions: jane drives from alabama to arkansas at 30 mph, then back to alabama at 50 mph without stopping. if the round-trip journey takes 4 hours, how much longer does it take jane to drive to arkansas than it takes her to drive back to alabama? a plane travels with headwinds at 300 mph from ny to paris. the return flight with tailwinds is undertaken at 700 mph. if the total flight time round-trip is 16 ours, how long does it take to go from ny to paris?

11h 12min from NY to Paris.

Step-by-step explanation:

2h 30min (2.5)×30mph=75m

1h 30min (1.5)x50mph=75m

1 hour longer when driving to Arkansas

11h 12min (11.2)×300mph=3360m

4h 48min (4.8)×700mph=3360m

11h 12min from NY to Paris.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
