Question

an aerolane is flying at a speed of 13 km /hr . what is speed in metre per second. how many kilometres will it cover in 2 hour 15 min?​

Answer 1

Answer:

Speed in metre per second = 3.61 m/s

Distance covered in 2 hr 15 min = 29.25 km

Step-by-step explanation:

According to the question speed of the aeroplane = 13 km/hr

Converting the speed of the aeroplane in m/s

$= > 13 \times \frac{1000}{3600} \\ \\ = > 13 \times \frac{5}{18} \\ \\ = > \frac{65}{18} \\ \\ = > 3.61m/s \:$

Distance covered by plane in 2 hr 15 min(2.25 hr) = Speed × Time

= 13 × 2.25

= 29.25 km

= 29250 m

Answer 2

Answer:

Speed in metre per second = 3.61 m/s

Distance covered in 2 hr 15 min = 29.25 km

Step-by-step explanation:

According to the question speed of the aeroplane = 13 km/hr

Converting the speed of the aeroplane in m/s

Distance covered by plane in 2 hr 15 min(2.25 hr) = Speed × Time

= 13 × 2.25

= 29.25 km

= 29250 m
