Answer

Answer:

3.5

Explanation:

Step1: Calculate morning - distance

The speed in the morning is 50 miles per hour and they drive for 3 hours. Using the formula $d = vt$ (distance = speed×time), the distance driven in the morning is $d_1=50\times3 = 150$ miles.

Step2: Calculate afternoon - distance

The total distance to the camp is 325 miles. So the distance to be driven in the afternoon is $d_2=325 - 150=175$ miles.

Step3: Calculate afternoon - time

The average speed in the afternoon is 50 miles per hour. Using the formula $t=\frac{d}{v}$, the time $t$ they drive in the afternoon is $t=\frac{175}{50}=3.5$ hours.
