Answer :
Answer:
Step-by-step explanation:
let the rate of travel of bicycle=x m/h
rate of travel of motor scooter=2x+2
time taken by motor scooter to travel 12 mi=12/(2x+2) hrs.
time taken by bicycle to travel 5 mi=5/x
as time is same
[tex]\frac{12}{2x+2}=5/x\\12x=5(2x+2)\\12x=10x+10\\12x-10x=10\\2x=10\\x=10/2=5\\rate~ of~ travel~ of~bicycle=5 m/h\\rate~ of~ travel~ of~ motor~ scooter=2x+2=2 \times 5+2=12 ~m/h[/tex]
