Question

At 10:00 a.m., two planes leave an airport flying in opposite directions. One plane travels northbound at 260 mph and the other travels southbound at 340 mph. At what time will the planes be 2,100 miles apart?

3:30 p.m.
1:30 p.m.
11:30 a.m.

Answer 1

1:30pm

260x + 340x = 2100

600x=2100

600x/600=2100/600

x=3.5 hours
