Question

A car cover a distance of 115½ km in 2⅓ hour. Find the distance covered by the car in hour? (Rational numbers)​

Answer 1

Answer:

The Car covers a Distance of 115 and a half kilometer in 2^1/3 hrs

Step-by-step explanation:

convert 115 n half to a basic fraction ==> 221/2 km

    ||        2 n 1/3     ||  ||    ||         ||         ==>  7/3 hrs..

So now,

           221/2 / 7/3  =  x / 1

          After simplification we get 221/2 = 7x/3

                                                       663/14= x

                                                       x = 47.3//

Therefore done!

Answer 2

Answer:

The distance covered by the car in 1 hr is 49.5 km

Step-by-step explanation:

Let the distance covered by the car in 1 hr be x.

Given,

• Distance covered (D₁) = 115.5 km
• Time Taken (T₁) = 2 hrs 20 min = 140 min
• Distance covered (D₂) = x km
• Time Taken (T₂) = 1 hr = 60 min

D₂ can be determined by the equation,

D₁T₂ = D₂T₁

∴ D₂ = $\frac{D_1T_2}{T_1}$

⇒ D₂ = $\frac{115.5 \times60}{140}$

⇒ D₂ = $\frac{6930}{140}$

⇒ D₂ = 49.5 km

∴ The distance covered by the car in 1 hr is 49.5 km
