To find out how many miles the vehicle will travel in 7 hours, we can use the concept of speed.
Given that the vehicle travels 195 miles in 3 hours, we can calculate its speed by dividing the distance traveled by the time taken:
Speed = Distance / Time
Speed = 195 miles / 3 hours
Speed = 65 miles per hour
Now that we know the speed of the vehicle is 65 miles per hour, we can find out how many miles it will travel in 7 hours.
We can use the formula:
Distance = Speed × Time
Distance = 65 miles per hour × 7 hours
Distance = 455 miles
Therefore, the vehicle will travel 455 miles in 7 hours at this rate.
