Answer 1

Answer:

Step-by-step explanation:

Circumference space of space straight a space circular space field equals 360 space km

Distance space covered space by space 1 st space cyclist space per space day equals 48 space km

rightwards double arrow Number space of space days space taken space by space 1 st space cyclist space to space cover space the space round equals 360 over 48 equals 7.5 space days equals 7.5 cross times 24 space hours equals 180 space hours

Distance space covered space by space 2 nd space cyclist space per space day equals 60 space km

rightwards double arrow Number space of space days space taken space by space 1 st space cyclist space to space cover space the space round equals 360 over 60 equals 6 space days equals 6 cross times 24 space hours equals 144 space hours

Distance space covered space by space 3 rd space cyclist space per space day equals 72 space km

rightwards double arrow Number space of space days space taken space by space 1 st space cyclist space to space cover space the space round equals 360 over 72 equals 7.5 space days equals 5 cross times 24 space hours equals 120 space hours

Now comma space the space shortest space distance space will space be space LCM space of space 180 comma space 144 space and space 120 equals 720

720 space hours equals 720 over 24 space days equals 30 space days

So they will meet in 30 days
