Question

what is the distance travelled by a car which travelled at a speed by 80km/hr for 3 hours and 30 mint. ​

Answer 1

Answer:

Given speed = 80 kmph,

Time = 3 hours 30 minutes = 3 1/2 hours = 7/2 hours

Distance = Speed x Time = 80 x 7/2 = 280 kms.

Therefore, the distance travelled by the car moving at a speed of 80 kmph for 3 hours 30 minutes is 240 kms.

I hope this may help you

Answer 2

Given:

A car travelled at a speed of 80km/hr for 3 hours and 30 mint.

To find:

The distance travelled by car.

Solution:

To answer this question, first of all, we should know that the distance 'd' travelled by an object that is moving at a speed 's' in time 't' is given by:

$d = s \times t$

Now,

proceeding to the solution, we have

Speed of the car = 80 km/hr

The time that was taken by the car = 3 hours and 30 mint.

$= 3 + \frac{30}{60} = \frac{7}{2} \: hours$

So,

distance travelled by car

$= 80 \times \frac{7}{2}$

$= 40 \times 7$

$= 280 \: km$

Hence, the distance travelled by car is 280 Km.
