Question

the speed of a car is 121/2 km/h. Find the distance covered in 21/5 hours.plzz give with explanation and answer in fraction​

Answer 1

✮ Distance (d) = 2541/10 km ✮

GIVEN:

• Speed(s) of car = 121/2 km/hr
• Time(t) taken by the car to cover the distance = 21/5 hours

FIND:

• What is the distance (d) covered by the car ?

SOLUTION:

We know that, the formula for finding the distance of the car is:-

✭ Distance = Speed $\times$ Time ✭

According to question:-

On Putting the values in the formula, we get

$\implies$ Distance = 121/2 $\times$ 21/5

$\implies$ Distance = 2541/10 km

❛ Thus, the car travels 2541/10 km in 21/5 hours with the speed of 121/2 km/hr ❜

✯ Extra Information ✯

➭ Speed = Distance/Time

➭ Time = Distance/ Speed

➭ Distance = The actual length covered by the body with respect to particular time is known as distance.

➭ Speed = The distance covered by the body along any direction is known as Speed.

Answer 2

$\large\underline\mathrm{Given:-}$

• Car speed = 121/2 km/HR
• Time = 21/5 he

$\large\underline\mathrm{To \: find}$

The distance covered by a car ?

$\large\underline\mathrm{Solution}$

$\implies$ Distance = speed/time

Now, put the value of the formula.

$\implies$ Distance = 121/2 × 21/5

$\implies$ 2541/10 km

Thus, the car travel 2541/10 km in 21/5 hr with the speed of 121/2 km/he.

• More Information:

$\implies$ Speed = Distance/Time

$\implies$ Time = Distance/Speed

$\implies$ Distance = Speed × Time

$\implies$ Distance = The actual length covered by the body with respect two particular time is known as distance.

$\implies$ Speed = the distance covered why the body along any direction is known as speed.
