Question

A car travels for 2hrs with a speed of 70km / hr, calculate the distance covered.​

Answer 1

Answer:

Let the distance travelled at 100 km/hr be x km.

Then, distance travelled at 50 km/hr is (170 - x) km.

Given,

100

x

+

50

(170−x)

=2

⇒

100

x+2(170−x)

=2⇒x+240−2x=200

⇒x=140km.

Answer 2

Answer:

Given :-

• A car travels for 2 hrs with a speed of 70 km/hr.

To Find :-

• What is the distance covered.

Formula Used :-

$\clubsuit$ Distance Formula :

$\bigstar \: \: \: \: \sf\boxed{\bold{\pink{Distance =\: Speed \times Time}}}\: \: \: \: \bigstar$

Solution :-

Given :

• Speed = 70 km/h
• Time = 2 hours

According to the question by using the formula we get,

$\implies \sf\bold{\purple{Distance =\: Speed \times Time}}$

$\implies \sf Distance =\: 70 \times 2$

$\implies \sf\bold{\red{Distance =\: 140\: km}}$

$\therefore$ The distance covered by a car is 140 km .
