Answer:
54kmph
Step-by-step explanation:
formula :
speed = distance/time
given :
biker speed : x kmph
chaser speed : 60kmph
chaser time : 4½hr : 9/2
biker time : 4½ + ½hr = 5 hrs
now....
chaser distance covered : speed × time
= 60 × 9/2 = 270 km
but....
chaser distance = biker distance = 270 km
hence.....
biker speed : distance/ biker time
= 270 / 5 = 54 kmph
