Question

please answer by solving​

Answer 1

Answer:

Speed = 240 m/s

Time = 1 and half hour

= 60 x 60 x 30 x 60

Distance travelled = speed x Time

Distance travelled= 60 x 60 x 60 x 30 x 240

Distance travelled= 1555200000

Answer 2

Answer:

Its option c) 1296 KM

so according to question,

it covers 240m per second.

so multiply it by 60 as 60 secs = 1 min

240 x 60 = 14,400

now this value is for 1 minute

multiply this by 60 as 60mins = 1 hr

14400 x 60 = 8,64,000 (pls save this value)

now divide the above value by 2, that will give us the distance covered in half and hour

8,64,000 divided by 2 = 432,000

now add the 2 values =

8,64,000  + 432,000 = 12,96,000m

now this is in metre, convert it to km

1m = 1000km

thus the answer is 1296 km
