Q9) A car takes 2 hours to reach a destination by traveling at a speed of 60 km/h. How long will it take when the car travels at the speed of 80 km/h?
Answer:
Solution:
Let the numbers of hours be x.
\therefore\frac{60}{80}=\frac{x}{2}
\Rightarrow\ x=\frac{60\times2}{80}
x=\frac{3}{2}
x=1\frac{1}{2}
The car will take 1\frac{1}{2}hours to reach the destination.
