Question

An Aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 5/3 hours, it must travel at a speed of

Answer 1

hi mate

240 kmph ~ 5 hours
x kmph ~ 1 2/3 hours = 5/3 hours

240/x = (5/3)/5
5/3x = 5 × 240
5/3x = 1200
x = 1200 : 5/3
x = 1200 × 3/5
x = 720 kmph

Answer 2

ʜɪ ᴍᴀᴛᴇ

240 ᴋᴍᴘʜ ~ 5 ʜᴏᴜʀs
x ᴋᴍᴘʜ ~ 1 2/3 ʜᴏᴜʀs = 5/3 ʜᴏᴜʀs

240/x = (5/3)/5
5/3x = 5 × 240
5/3x = 1200
x = 1200 : 5/3
x = 1200 × 3/5
x = 720 ᴋᴍᴘʜ
