Question

Rakhi covered a distance of 15 1/10 out of this she covered 5 1/4 km by train and 6 1/2 km by bus and rest by taxi how many km did she cover by taxi

Answer 1

Answer:

Step-by-step explanation:

Total distance covered = 15 1/10

Distance covered by train = 5 1/4 or 21/4 ( 4x5+1 )

Distance covered by bus = 6 1/2 or 13/2

Distance covered by taxi =? Let this be x.

So, ATQ 21/4 + 13/2 + x = 151/10

=> 21 + 26 + 4x 151

------------------------ = ------

4 10

=> (47 + 4x) 10 = (151) 4 (cross multiply)

=> 470 + 40x = 604

=> 40x = 604 - 470

=> 40x = 134

=> x= 134/40

=> x= 3 7/20

Therefore distance covered by taxi is 3 7/20 km.

Answer 2

Answer:

3 7/20 km

Step-by-step explanation:

Total distance covered = 15 1/10

Distance covered by train 5 1/4 or 21/4 (4×5+1)

Distance covered by bus = 6 1/2 or 13/2

Distance covered by taxi = ? Let this be x

So, 21/4 + 13/2 + x = 151 / 10

=> 21 + 26 + 4x = 151

4 10

=> (47 + 4x )10 = (151)4 ( cross multiply )

=> 470 + 40x = 604

=> 40x = 604 - 470

=> 40x = 134

=> x = 134/40

=> x = 3 7/20

Therefore distance covered by taxi is 3 7/20.
