Question

A car travels a distance of 180 km in 3 hours and a train travels a distance of 320 km in 4. Find the ratio of the speeds, if,
SPEED =
$\frac{distance}{time \: taken}$
​

Answer 1

Hello :D ✨

Step-by-step explanation:

✔First the speed of the car:

\large{speed=distance/time}speed=distance/time

\large{speed=180km/3hours}speed=180km/3hours

\large{speed=60km/hour.....(1)}speed=60km/hour.....(1)

✔Speed of the bus:

\large{speed=distance/time}speed=distance/time

\large{speed=320km/4hour}speed=320km/4hour

\large{speed=80km/hour.....(2)}speed=80km/hour.....(2)

✔Now Dividing (1) and (2) :

\large{60km/h/80km/h}60km/h/80km/h

❤Ratio of speed of car and train is

✔ 3:4

Answer 2

Answer:

Speed 1 = d¹/t¹ = 180/3 = 60km/hr

Speed 2 = d²/t² = 320/4 = 80km/hr

Ratio = Speed¹/Speed² = 60/80 = 3/4 = 3: 4 is the answer.
