Question

a car travels 120 km in 3 hours and a train travels 100 km in 2 hours. find the ratio of their speeds​

Answer 1

Answer:

The ratio of their speeds will be 4/5

Answer 2

Formula:-

$\underline{\boxed{\bf Speed = \dfrac{Distance}{time}}}$

Solution:-

$\implies \sf \: speed \: of \: 1st \: car = \dfrac{ \cancel{120}}{ \cancel{3}} = 40 \: km \: per \: hr \\ \\ \implies\sf speed \: of \: 2nd \: car = \frac{ \cancel{100}}{ \cancel{2}} = 50 \: km \: per \: hr \\ \\ \implies\sf \: ratio = \frac{speed \: of \: 1st \: car}{speed \: of \: 2nd \: car} = \frac{4 \cancel0}{5 \cancel0} = \frac{4}{5}$

hence the required answer is 4:5
