Question

a scooterist covers 48 km in 1hr and a car drives covers 120km in 2hr find the ratio of their speed​

Answer 1

A scooterist covers 48 km in 1hour and car drive covers 120km in 2hours. find the ratio of their speeds. - 12947472. ... Hence The ratio of their speed is 4:5.

Step-by-step explanation:

Distance traveled by scooterist = 48 km

Time = 1 hour

\begin{gathered}Speed = \frac{Distance}{Time}\\Speed = \frac{48}{1}\\Speed = 48 km/hr\end{gathered}

Speed=

Time

Distance

Speed=

1

48

Speed=48km/hr

Distance traveled by car = 120 km

Time = 2 hours

\begin{gathered}Speed = \frac{Distance}{Speed}\\Speed =- \frac{120}{2}\\Speed = 60 km/hr\end{gathered}

Speed=

Speed

Speed=−

120

Speed=60km/hr

Ratio of their speed = \frac{48}{60}=\frac{24}{30}=\frac{8}{10}=\frac{4}{5}
