Question

racing car covered 600 kilometre in 3 hour 20 minutes find its speed in metre per second how much distance will the car cover in 50 second ​

Answer 1

Answer:

speed=50m/s and distance under 50 seconds=2500m

Step-by-step explanation:

Let d be the distance travelled, t the time and s the speed of the car. Then we have the following relation

$d = 600 \: km \\ d = 600 \times 1000 \: m \\ d = 600000 \: m \\ t = 3 \: hrs \: 20 \: mins \\ t = 3 + \frac{20}{60} \: hrs \\ t = (3 + \frac{20}{60} ) \times 60 \times 60 \: seconds \\ t = 10800 + 1200 \: s \\ t = 12000 \: s \\ s = \frac{d}{t} \\ s = \frac{600000}{12000} \: \frac{m}{s} \\ s = \frac{600}{12} \: \frac{m}{s} \\ s = 50 \: \frac{m}{s}$

Again, for distance travelled under 50 seconds, we have

$d = st \\ d = 50 \times 50 \: m \\ d = 2500 \: m$
