Question

what is the speed of a car that travels 700 km in 3 hours and 30 minutes​

Answer 1

The speed of a car is 200 $\dfrac{km}{hr}$.

Step-by-step explanation:

Given,

The total distance travelled by car(d) = 700 km and

Time(t) = 3 hours and 30 minutes​ = 3 + $\dfrac{30}{60}$ = 3.5 hours

[ ∵ 1 Hour = 60 Minutes]

To find, the speed of a car(s) = ?

We know that,

Speed(s) = $\dfrac{Distance(d)}{Time(t)}$

$= \dfrac{700km}{3.5hours}$

= 200 $\dfrac{km}{hr}$

Thus, the speed of a car is 200 $\dfrac{km}{hr}$.

Answer 2

Answer:

The speed of the car will be 200 km/hour

Step-by-step explanation:

Total distance=700 km

Total time=3 hour 30 mint= 3 hour $\frac{30}{60}$ mint.=3.5 mint.

We know that, Speed= $\frac{Distance}{Time}$

So putting the value on the above equation,we will get that

 Speed of the car=$\frac{700}{3.5}$=200 km/hour.
