Explain how knowing 50×4 helps you find 500×400

1 answer:

Andre45 [30]3 years ago

8 0

5x4= 20
50x40=200
500x400=200000
Do you see the pattern? 5x4=20, which means that all you need to do is add the zeros. 50x40 has two zeros, which means it should equal 200.

In how many hours would they be 800 km apart?

Anestetic [448]

The two cars (a and b) will be 800 km apart after 10 hours.

<h3>What is the average speed of a car?</h3>

The average speed of a car is the total distance traveled by a car within a specific period of covering such distance.

From the given information:

If the speed of car A (v_a) = 30 km/hr; and
The speed of car B (v_b) = 50 km/hr

The distance between both cars will be the hours they will meet:

i.e.

$\mathbf{(v_a \times t)+(v_b\times t)= 800 \ km}$

$\mathbf{(30 \times t)+(50\times t)= 800 \ km}$

30t + 50t = 800

80t = 800

t = 800/80 hrs

t = 10 hrs
