Question

A train travels at speed of 50 km/hr for 0-5 houre and for next 0-20 hours it
travels with speed of 30 km/hr. What is the average speed of the train ?​

Answer 1

Answer:

Dist travelled at 50kmph

=speed*time

=50*0.5=25km

for next 0.2 hr it travels

at 30kmph. So dist covered is

30*0.2

=6 km

Explanation:

so total dist=25+6=31km

done in

0.5+0.2=0.7 hr

so ave speed

=31/0.7

=44.28 kmph ANSWER
