The following week the company was hired for a 225 mile move. If each truck traveled at hte same speed it has the previous week how long did the trip take for each truck?

I added a screenshot of the original question.

Now, first we will need to calculate the speed of each truck and then get the time that each of them will take to travel the 225 miles.

The basic rule that we will use for this question is:

velocity = distance / time

Part (a) : getting the velocity of each truck:

For the large truck:

We are given that the truck took 4 hours to travel 180 miles. Therefore:

velocity of large truck = 180 / 4 = 45 miles/hour

For the small truck:

We are given that the truck took 3 hours to travel the same 180 miles. Therefore:

velocity of small truck = 180 / 3 = 60 miles/hour

Part (b) : getting the time required for each truck to travel 225 miles:

For the large truck:

We have the distance = 225 miles and the velocity = 45 miles/hour. Therefore:

velocity = distance / time

time = distance / velocity = 225 / 45 = 5 hours

For the small truck:

We have the distance = 225 miles and the velocity = 60 miles/hour. Therefore:

velocity = distance / time

time = distance / velocity = 225 / 60 = 3.75 hours
