Question

6. An arrow can travel at a speed of 648 km/h. How long does the arrow take to travel a distance
2400 m?
​

Answer 1

Answer:

The arrow will take 13.33 seconds to travel a distance of 2400 m.

Step-by-step explanation:

To convert 648 km/h into m/s,

Multiply 648 by 5/18, which gives 180 m/s

Distance to be travelled=2400m

So it would take 2400/180 seconds, which is 13.33 seconds.

Hope it helps you!

Answer 2

ANS = 7.5 SEC

Step-by-step explanation:

SPEED TAKEN - 648 KM/H

DISTANCE GIVEN - 2400 M

TIME REQUIRED

SO WE NEED TO CONVERT 2400M TO KM FOR THAT DIVIDE 2400 BY 1000

=>2.4 KM

THEN WE HAVE TO CONVERT 648 KM/H TO M/S FOR THAT MULTIPLY 648 BY 5 THEN DIVIDE IT BY 18

=>180 M/S

So, TIME = DISTANCE

SPEED

=> 2.4 km × 10 ÷ 180 m/s

= 7.5 Sec
