according to the question:
cyclist complete a journey in 31 by 2 hours
it means we have to to count it a journey in 1 hour for this:
31/2=12.5/ hour
again the the speed of the first half distance is 15 km per hour
it means we have to multiply 12.5 into 15
: 12.5×15=18.75
then we have to multiply second half distance that is 20 km per hour
:18.75×20=375
then you have to add all the distance that is
=406.25
