Given :- Distance is 3240 km

Time is 2 hrs and 15 minutes

= 120 + 15 = 135 minutes

$= \frac{135}{60 } =$$\frac{9}{6}$$= 4.2⠀hours$

$Speed = 3240 \times \frac{9}{4}$

$= 1440⠀km/hr$

$1440 \times \frac{5}{18}$$400 m/sec$

Answer 2

Speed = distance divided time
Speed = 3240km divided by 2 hrs and 15min
Speed = 3240000 divided
8100s = 400
Speed = 400m/s
