Ahelicopter leaves an airport and flies south at 180 mi/h. thirty minutes later, an airplane leaves the airport and follows the same route as the helicopter, only at a higher elevation. the airplane is flying 330 mi/h. how many minutes will it take for the airplane to catch up with the helicopter? (hint: 30 minutes is 12 hour.)

36 minutes

Step-by-step explanation:

helicopter 1 is ahead of helicopter 2 by 90 miles

the difference in their speeds is 150 mph

90/150=3/5 of hour

3/5*60=36 minutes

i think ur answer is   (3,-1)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
