Answer
hours

Answer 1

25 hours

Explanation:

Given

• It took 39 hours in total to get to his grandmother's house
• Walking and train transit takes 14 hours together

Solving

• Total time = Time (walking) + Time (train) + Time (bus)
• 39 hours = 14 hours + Time (bus)
• Time (bus) = 39 - 14 = 25 hours

Answer 2

What we know:

• 39 hours is the total amount of time spent on the trip.
• 14 hours spent with both walking and the train.

Our challenge:

• To figure out how many __ hours were spent on the bus.

Let's set up an equation,

-we'll assume that 'x' are the unknown hours spent on the bus.

The unknown hours spent on the bus plus the hours spent both on walking/and the train will equal a total of 39 hours.

So,

14 + x = 39

Solve for x;

-14 -14

x = 25, the hours Jerry spent riding on the bus is 25 hours.
