Question

sunanda travelled 36 km 500m by car and 132 km 255 m by train . if he had to travel 432 km in all , how much distance is still left to cover?​

Answer 1

$\huge\bf\underline{Answer}$

The distance still left to covered by Sunanda is 263 km 245 m.

Solution:-

Given,

Distance travelled by Sunanda by car = 36 km 500 m

Distance travelled by Sunanda by train = 132 km 255 m

Total distance Sunanda travelled = 432 km

Total distance covered by Sunanda by car and train :-

= (Distance covered by car + Distance covered by train)

=(36 km 500 m + 132 km 255 m)

= 168 km 755 m

Therefore, Distance still left to cover :-

= (Total Distance to travel - Total distance covered by car and train)

=(432 - 168.755) km

= 263 km 245 m

Hence, The distance still left to cover is 263 km 245 m

Answer 2

Answer:-

S = 263.245 km

Given:-

Distance travelled by car = 36 km 500m

Distance travelled by train = 132 km and 225 m.

Total distance had to travel = 432 km

Solution :-

First, change the distance in km.

1 km = 1000 m

500 m = 1/2 km

Let the distance travelled by car = S

Distance travelled by car = $S = 36 + \dfrac{1}{2}$

$S = \dfrac {72+1}{2}$

$S = \dfrac{73}{2}$

$S = 36.5km$

Let the distance travelled by train = S"

then,

$S" = 132 + \dfrac{255}{1000}$

$S" = 132 + 0.255$

$S" = 132.255km$

Now, Distance left to cover = 432 - (S + S" )

$= 432 - ( 36.5 + 132.255 )$

$= 432 - 168.755$

$= 263.245 km$

hence, distance left to cover is 263.245 km
