Answer 1

Answer:

he traveled 300 km by ship

hope it helps you thanks

Step-by-step explanation:

speed of train =65km/h

speed of ship =25km/h

given total distance =430 km

65=distance/time

25=distance/time

total distance =430=65×a+25×(a+10)

where a is time spent while traveling ,it's 10 hour more on traveling by ship

430=65a+25a+250

90a=180 a=2

so he traveled 2 hours by train and 12 hours by ship

to verify

by train 65 km /h

in 2 hours =130 km

by ship 25km/h

in 12 hours =300 km

total distance 300+130=430

so non of the given option is right
