Question

a fast train converse 320 km in 3 hours 20 minutes how much time will it take to cover a distance of 90 kilometre ​

Answer 1

Step-by-step explanation:

Speed= distance travelled / time taken 320km/3hr20m

=320/3*20/60=320/3*1/3

=320/10/3=320*3/10=

960/10=96km.

Time taken=distance travelled/speed =90km/96km/hr=90/96hrs=15/16hrs=15/16*60=

900/16.- fraction converted to mixed fraction

=56*4/16=56*1/4=56(1/4*60)

56mts and 15 sec.
