Question

A train travels 90 km in 1 1/2 hrs. what distance will it travel 3 hrs 30 mins at the same speed?

Answer 1

Answer: 210Kms. in 3h. and 30min.

Step-by-step explanation:

The train travels 90Kms. in 1h. and 30min.

We can write 1h. and 30min. = 1.5hours

Then,

Speed = Distance/Time

= 90/1.5

= 60Kms/h

Speed of the train is = 60Kms/h

So,

Speed=60Km/h, Time=3h and 30min=3.5h, Distance=?

Speed=Distance/Time

or

Distance=Speed×Time

=60×3.5

=210Kms
