Question

if a car cover 300km in 4 hours and 30 minutes, then find the distance covered by it in 1 hour ​

Answer 1

Given : Distance = 300km

Time= 4hour 30 minutes = 270 minutes

Speed=Distance/ Time

speed=300/270= 10/9

Time=1 hour

distance=speed×time = 10/9.×60=20/3

I am not confirm that it is right or wrong

sorry for it..

Answer 2

Given data :

➜ Distance covered by car = 300 km

➜ Time taken by car = 4 hour and 30 minutes

Solution : Now, according to given data,

➜ Time taken by car = 4 hour and 30 minutes

Here, we know that, 1 hour = 60 minutes

Hence, 30 minutes = 30/60 hour = 1/2 hour.

So, here

➜ Time taken by car = 4 ½ hour

➜ Time taken by car = {(4 * 2) + 1}/2 hour

➜ Time taken by car = {8 + 1}/2 hour

➜ Time taken by car = 9/2 hour

Now, by formula of speed

➜ Speed = Distance/Time

➜ Speed = 300/(9/2)

➜ Speed = (300 * 2)/9

➜ Speed = 600/9

➜ Speed = 200/3 km/hr

Now, to find out distance covered by car in 1 hour constant speed 200/3 km/hr

➜ Speed = Distance/Time

➜ 200/3 = Distance/1

➜ Distance = 200/3 km or 66.67 km

Answer : Hence, the distance covered by car in 1 hour constant speed 200/3 km/hr is 200/3 km (66.67 km).

{More info :

➜ Speed = 200/3 km/hr

➜ Speed = (200/3) * (5/18) m/s

➜ Speed = (200 * 5)/(3 * 18) m/s

➜ Speed = 1000/54 m/s

➜ Speed = 500/27 m/s or 18.5185 m/s and

➜ Distance = 200/3 km

➜ Distance = (200/3) * 1000 m

➜ Distance = (200 * 1000)/3 m

➜ Distance = 2/3 * 10⁵ m}
