miles in the next hour. the last hour of their trip, they drive 75 miles.
calculate the average speed of talías car during the trip. give your answer to the nearest whole number.

mph

Explanation:

Step1: Calculate total distance

Total distance \(d = 100+30 + 75=205\) miles.

Step2: Calculate total time

Total time \(t=2 + 1+1 = 4\) hours.

Step3: Calculate average speed

Average speed \(v=\frac{d}{t}=\frac{205}{4}=51.25\approx51\) mph.

Answer:

\(51\) mph
