Question

a train covers a distance of 51 km in 45 minutes how long will it take to cover 221 kilometre
​

Answer 1

Step-by-step explanation:

to cover 51 km a train takes 45 min

to cover 1 km a train takes 45/51 min

to cover 221km a train takes (45*221)/51 min

=195min

= 3 hr 15min

2nd Method

45 : 51 : : x : 221

product of external = product of internal

45 * 221 = 51 *X

9945 = 51x

x = 9945/51

= 195 min

= 3hr 15 min
