Find how fast she runs 1 km:

18/2 = 9 minutes.

So we know have K = 9t

Subtract 18 from both sides:

K-18 = 9t -18

Rewrite the right side:

K-18 = 9(t-2)

Riya took a train from his hometown to Mumbai . The journey lasted for 3 hrs 35 minutes . The train reached the station at 9:15
zhenek [66]

Answer: 5:40 am

Step-by-step explanation:

The train reached the station at 9:15 am after having travelled for 3 hrs 35 minutes.

The time the train departed from Riya's hometown was the time it arrived in Mumbai station less the time taken to travel:

= 9:15 - 3:35

First deduct the 3 hours:

= 9:15 - 3

= 6 : 15 am

Remove the 35 minutes by first removing the 15 minutes

= 6:15 - 15

= 6:00 am

Then remove the rest of the 35 minutes which is 20 minutes:

= 6:00 - 20 minutes

= 5:40 am
