Question

A train travels 600 km in 3 hour 45 mins. Find its speed.

Answer 1

Distance travelled by the train = 600km

Time taken = 3hr 45min = [3+ 45/60]hr

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= (3+ 3/4)hr

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 15/4 hr

$time \: = \frac{distance}{speed} \\ \: \: = \frac{600}{ \frac{15}{4} } \\ = \frac{600 \times 4}{15} \: = 160 \: km \: per \: hour$

Hope it helps ✌✌✌
