Question

a car covers a distance of 7km in 5min.Its speed is _________.please tell in process.
​

Answer 1

Answer:

Speed : 84 km/h

Step-by-step explanation:

Distance = 7 km

Time = 5 mins = 5/60 hr = 1/12 hr (Converting minutes into hours.)

Speed = Distance / Time

Speed= 7/1/12 = 7 x 12

Speed = 84 km/hr

Therefore, Its speed is 84 km/hr

Answer 2

Given: A car covers a distance of $7$km in $5$min.

We have to find the speed of the car.

As we know that the speed is calculated by a formula:

$Speed=\frac{Distance}{Time}$

We are solving in the following way:

We have,

A car covers a distance of $7$km in $5$min.

We know that $1hr=60min$

Therefore, $5min=\frac{5}{60} hr$

So, the speed of the car will be:

$Speed=\frac{Distance}{Time}$

$=>Speed=\frac{7}{\frac{5}{60} } \\\\=>Speed=\frac{7}{5} \times\frac{60}{1} \\\\=>Speed=84km/hr$

Hence, the speed of the car will be$84km/hr$.
