Question

A train took 4 hours and 30 minutes to cover 360 kilometres.what is it's average speed.step by step answer

Answer 1

Time taken = 4h 30 mins.
=4+30/60 hours
=4.5 hours

Total distance=360km

Avg. Speed
$\frac{total \: distance \: travelled}{time \: taken \: to \: cover \: the \: distance}$
$= \frac{360}{4.5} \\ = \frac{360 \times 10}{45} \\ \frac{40 \times 10}{5} \\ = 8 \times 10 \\ = 80km {h}^{ - 1}$
