For motorcycle
Distance = 160 km
Time taken = 2 hrs
Speed = Distance/Time = 160/2 = 80 km/hr
For Scooter
Distance = 270 km
Time taken = 3 hrs
Speed = Distance/Time = 270/3 = 90 km/hr
Ratio of Speed of Scooter to Speed of Motorcycle = Speed of scooter / Speed of motorcycle
= 90/80 = 9/8
Your answer is 9:8
Distance = 160 km
Time taken = 2 hrs
Speed = Distance/Time = 160/2 = 80 km/hr
For Scooter
Distance = 270 km
Time taken = 3 hrs
Speed = Distance/Time = 270/3 = 90 km/hr
Ratio of Speed of Scooter to Speed of Motorcycle = Speed of scooter / Speed of motorcycle
= 90/80 = 9/8
Your answer is 9:8
