Answer

Explanation:

Step1: Calculate distance driven on first day

Distance = Speed×Time. Speed is 65 miles per hour and time is 4 hours. So distance on first - day $d_1=65\times4 = 260$ miles.

Step2: Calculate remaining distance

Total distance $D = 455$ miles. Remaining distance $d_2=D - d_1=455 - 260=195$ miles.

Step3: Calculate time for second - day drive

Time = Distance÷Speed. Speed is 65 miles per hour and remaining distance $d_2 = 195$ miles. So time $t=\frac{195}{65}=3$ hours.
