The ratio of the speeds of two scooters is 9 : 5. If the second scooter nuns 75 km in 6 hours, then what is the speed (in km/h) of the first scooter?

22.5

Distance = Speed × Time

Speed = \(\frac{DIstance}{Time}\)

Speed of 2nd scooter = \(\frac{75}{6}\) = \(\frac{25}{2}\) km/h

Now ,

Ratio of Speed of 1st scooter to 2nd scooter = 9 : 5

According to question ,

5R = \(\frac{25}{2}\)

1R =  \(\frac{5}{2}\)

9R = 9 × \(\frac{5}{2}\) = 22.5

So , speed of 1st scooter is 22.5 km/h
