Question

1) Flying against a head wind, a plane could fly 3000 km in 6 hr. The plane would require only 5 hours for the return trip with no change in wind. Find the wind speed and air speed of the plane?
Rate=distance/time

Answer 1

$3000 \times 5 = \div 6$

3000×5=15000.so 6÷15000=2500

so the wind speed us 2500 km per hour
