The speed of A=40km/h
The speed of B=50km/h
then the speed of A=60minutes =40km
the distance covered in 1 minute =40/60 =2/3
again
the speed of B = 60 minutes = 50km
then the distance covered in 1 minute = 50/60 =5/6
according to question
A' cover a distance in 25 mintes = 2/3 ×25 =50/3km
Then B' =50/3÷5/6 =50/3 ×6/5 =20
B covers the same distance in 20 minutes
The speed of B=50km/h
then the speed of A=60minutes =40km
the distance covered in 1 minute =40/60 =2/3
again
the speed of B = 60 minutes = 50km
then the distance covered in 1 minute = 50/60 =5/6
according to question
A' cover a distance in 25 mintes = 2/3 ×25 =50/3km
