Kylie explained that (–4x + 9)2 will result in a difference of squares because (–4x + 9)2 = (–4x)2 + (9)2 = 16x2 + 81. Which sta

It is 170 miles from Bruce's house to the city where his brother lives. On his last trip to visit his brother, he drove for 2 ho
Rom4ik [11]

Speed of Bruce for the rest of the trip is 30 miles/hour.

Step-by-step explanation:

  • Step 1: Total distance = 170 miles. In the trip Bruce's speed = 55 miles/hour. So, in 1 hour, distance covered = 55 miles. Find distance covered in 2 hours and the distance of the last part.

Distance covered in 2 hours = 2 × 55 = 110 miles

Remaining part of the trip = 170 - 110 = 60 miles

  • Step 2: Find the speed of Bruce in the remaining part of the trip when time = 2 hours and distance = 60 miles.

Speed = Distance/Time = 60/2 = 30 miles/hour
