Question

1 km decrease by 30percent​

Answer 1

Answer:

1 km decrease by 30% = 700 m

Step-by-step explanation:

As we know that,

1 km = 1000 m

The 30% of the 1 km is:

=> 30 × 1000 / 100

=> 300

.°. 30% of 1km = 300 m

Now,

We have to decrease 30% of 1km in 1km.

=> 1 km - 30% of 1 km

=> 1km - 300 m

=> 1000 m - 300 m

=> 700 m

.°. 1 km decrease by 30% = 700 m
