Question #1

An executive drove from home at an average speed of 30 mph to an airport where a helicopter was waiting. The executive boarded the helicopter and flew to the corporate offices at an average speed of 60 mph. The entire distance was 150 mi. The entire trip took 3 h. Find the distance from the airport to the corporate offices.

I think the equation should start like this: Rate (r) * Time, (t) = Distance (D)

Good start -

now assume that

distance of airport to office = D

time to tarvel from airport to office = D/60

distance of home to airport = 150 - D

time to tarvel from home to office = (150 - D)/30

Now use the given total time to travel to formulate your equation
