Answer: Speed of Car A=35km/h
Speed of car B=25km/h
Step-by-step explanation:
Let speed of car A be x and car B be ykm/h
case1:
distance travelled by A=8x km
" " B=8y km
therefore,8x=80+8y
x-y=10----1
case2
distance travelled by 1hr 20mins
distance travelled by A=(4/3)x
" " " B=(4/3)y
therefore,4x/3+4y/3=80
x+y=60------2
from 1 and 2
x=35km/h and y=25km/h
