The ratio of speeds is 1:3

Step-by-step explanation:

Given:

• Speed of a cycle is 15 km/hr

• Speed of scooter is 45 km/hr

To Find:

The ratio of speed of cycle and scooter.

Solution:

Let, The ratio be ‘x’.

The ratio of cycle is 15 km/hr and scooter is 45 km/hr.

$\implies \sf Ratio \ = \ \dfrac{Speed \ of \ cycle}{Speed \ of \ scooter}$

$\implies \sf Ratio \ = \ \dfrac{15}{45}$

$\implies \sf Ratio \ = \ \dfrac{1}{3}$

$\implies \sf Ratio \ = \ 1:3$

$\therefore$ The ratio of the cycle and scooter is 1:3.
