Question

if two trains travel at 85 km per hour and 90 km per hour for 9 hours and 10 hours respectively then the ratio of their distances covered is​

Answer 1

Speed of a train A=85 km per hr

time it took for travelling=9 hrs

Distance by train A=Speed×Distance

=85×9=765km

Speed of train B=90km per hour

time=10 hrs

Distance by train B=Speed ×time

=90×10=900km

Ratio of distance covered by both the trains=765/900=17:20
