Distance = s × t
240 × 5
1200 km
Speed of aeroplane when it is cover the same distance in 1 and 16 min
Speed = D by time
= 1200÷ 5/3
= 1200× 3/5
= 240×3
= 720 km/hr
240 × 5
1200 km

Distance = (240 × 5) = 1200 km.
Speed = Distance/Time
Speed = 1200/(5/3) km/hr. [We can write 5/3 hours as 5/3 hours]
∴ Required speed = (1200×3/5) km/hr=720 km/hr.
