Answer:
17 minute 30 seconds.
Step-by-step explanation:
To solve this question we will apply unitary method.
∵ in 4 days train station clock gains = 7 minutes
∴ in 1 day the clock will gain = [tex]\frac{7}{4}[/tex] minute
∴ in 10 days train clock will gain = [tex]\frac{7}{4}\times 10[/tex]
= [tex]\frac{7\times 10}{4}[/tex]
= [tex]\frac{70}{4}[/tex]
= [tex]\frac{35}{2}[/tex]
= [tex]17\frac{1}{2}[/tex] minutes
or 17 minutes 30 seconds.
