Shawn's engineering club is taking a trip by bus to a robotics fair. The fair is 175 miles from Shawn's school. The bus driver plans to stop and refuel after 2 hours, then complete the trip. The bus driver plans to drive at an average speed of 50 miles per hour. How many hours will the second part of the trip take?
Write your answer as a whole number or a decimal.
The first part of the trip will take 2 hours to reach the refueling stop.
After the refueling, the remaining distance is 175 - 2 * 50 = 75 miles.
The time it will take to complete the remaining distance is 75 / 50 = <<75/50=1.5>>1.5 hours.
Therefore, the second part of the trip will take 1.5 hours. Answer: \boxed{1.5}.
To find out how many hours the second part of the trip will take, we need to subtract the time spent refueling from the total time of the trip.
The first part of the trip takes 2 hours for refueling.
Therefore, the remaining time for the second part of the trip is total time of the trip minus refueling time:
Total time of the trip = 2 hours + time for the second part of the trip
The total distance of the trip is 175 miles.
The bus travels at an average speed of 50 miles per hour.
To find the time for the second part of the trip, we can use the formula:
Time = distance / speed
The remaining distance for the second part of the trip is:
Remaining distance = Total distance of the trip - Distance traveled during refueling
Distance traveled during refueling = speed * time for refueling
Distance traveled during refueling = 50 miles per hour * 2 hours
Distance traveled during refueling = 100 miles
Therefore, the remaining distance for the second part of the trip is:
Remaining distance = 175 miles - 100 miles
Remaining distance = 75 miles
To find the time for the second part of the trip, we can now use the formula:
Time = Remaining distance / speed
Time = 75 miles / 50 miles per hour
Time = 1.5 hours
So, the second part of the trip will take 1.5 hours.
To find the number of hours it will take for the second part of the trip, we first need to determine how long it will take to complete the first part of the trip.
The bus driver plans to stop and refuel after 2 hours of driving. Since the average speed of the bus is 50 miles per hour, in 2 hours, the bus will have traveled 2 * 50 = 100 miles.
Therefore, after the refueling stop, there will be 175 - 100 = 75 miles remaining to reach the fair.
To find the number of hours it will take to cover the remaining 75 miles, we can use the formula: Time = Distance / Speed.
Time = 75 miles / 50 miles per hour = 1.5 hours.
So, the second part of the trip will take 1.5 hours.
