PLS TELL HOW YOU CAN CONVERT 3KM 50 M AND 1KM 250M TO KM

Answer 1

Answer:

Here is your answer:

Cycling- 3 km 50 m

Running- 1 km 250 m

Swimming- ?

If the total distance is 5km how much distance is covered in swimming?

=  3km 50m + 1 km 250m

= 4 km 300 m

= 4 km 300 m - 5km 000m

= 0 km 700m

or

Total distance for the triathlon=5 km

Distance covered for cycling=3km 50m

Distance covered for running=1km250m

So, total distance covered in the two activities=[3km 50m+1km 250m]= 4km 300m

Hence distance covered in swimming= 5km-4km 300m. (5km=5000m &4km 300m=4300m)

Therefore distance covered in Swimming= (5000m-4300m) = 700m

So distance covered in Swimming is 700m

Here is your answer
1 km = 1000 m
1 m = 1/1000 km

By Cycling cover = 3 km 50 m
$= 3 + \frac{50}{1000} \\ = 3 + 0.050 \\ = 3.050 \: km$
BY Running cover s = 1 km 250 m

$= 1 + \frac{250}{1000} \\ = 1 + 0.250 \\ = 1.250 \: km$
Let by Swimming cover x km

Total Distance = 5 km

ATQ
$3.050 + 1.250 + x = 5 \\ 4.300 + x = 5 \\ x = 5 - 4.300 \\ x = 0.700 \: km$

Now
0.700 km = 0.700× 1000 m
= 700 m

Therefore by Swimming cover a distance of 700 m
