Question

A train travels a distance of 1000 kilometre 400 metre in 15 1/2 hours 30 minutes what is the average speed of the train with steps solution ​

Answer 1

Step-by-step explanation:

☆ GIVEN :-

DISTANCE TRAVEL BY TRAIN

= 1000 KM 400 M

= 1400 METER = 1.4 KM

TOTAL TAKEN TIME = 151/2 h. 30 Min$</strong><strong>15 \frac{1}{2} h \: \: 30min \\ \\ = \frac{31}{2} h \: \: + \frac{30}{60} h \\ \\ = \frac{31}{2} + \frac{1}{2} \: \: h \: \: \: \: \: \\ \\ = \: \frac{32}{2} = \: \: 16 \: \: h$

$AVERAGE \: \: \: SPEED = \frac{ distance \: \: travelled}{total \: \: taken \: \: time} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1.4}{16} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 0.0875 \: km \: per \: hour$
