Shawn's engineering dub 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. Submit

To determine how many hours the second part of the trip will take, we first need to calculate how far the bus travels in the first 2 hours. 1. **Calculate the distance traveled in the first 2 hours:** \[ \text{Distance} = \text{Speed} \times \text{Time} = 50 \text{ miles/hour} \times 2 \text{ hours} = 100 \text{ miles} \] 2. **Calculate the remaining distance to the fair:** \[ \text{Remaining Distance} = \text{Total Distance} - \text{Distance Traveled} = 175 \text{ miles} - 100 \text{ miles} = 75 \text{ miles} \] 3. **Calculate the time required to travel the remaining distance at the same speed:** \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{75 \text{ miles}}{50 \text{ miles/hour}} = 1.5 \text{ hours} \] Therefore, the second part of the trip will take **1.5 hours**.
