Given

An aeroplane covers a certain distance at a speed of 240 km/hr in 5 hours. To cover the same distance in 1 2/3 hours

Concept used

Time and Distance

Calculation

Distance = Speed × Time

Distance = 240 × 5

Distance = 1200 km

Speed = Distance / time 

Speed = \(\frac{{1200}}{{\frac{5}{3}}}\)

Speed = 720 km/hr
