Answer:

Total distance covered by airplane is 3330 km

Explanation:

Distance covered in speed of v= 696 km /hr for t = 4 hours is

$x_{1}=v \times t\\x_{1}=696 \times 4\\x_{1}=2784 km$

Convert given speed in km/min, then distance covered in 35 minutes at speed of 936 km/hr is

$x_{2}=\frac{936}{60} \times 35\\x_{2}==546 km$

Total distance covered by airplane is

$x = x_{1}+x_{2}\\x =2784 +546\\x=3330 km$

Total distance covered by airplane is 3330 km
