Question

A red kite is 100 feet off the ground and is rising at 8 feet per second. A blue kite is 180 feet off the ground and is rising at 5 feet per second. How long will it take for the red kite to be higher than the blue kite? Round your answer to the nearest second

Answer 1

the difference in height is 80 ft.
the difference in speed is 3ft/s (feet per second)
divide 80 by 3, you get about 27 seconds. the real answer is close to 26.66 seconds

Answer 2

thanks

Answer 3

Red Kite: 100/8=12.5
Blue Kite: 180/36
36-12.5= 23.5 seconds or rounded= 24 seconds.
