The distance (in miles) traveled when driving at a certain speed s for 24 hours, then driving 17 miles/hour faster for another hour. Express the distance in terms of s

Answers

The total distance in terms of 's' will be : (25s+17) miles

Explanation

We know that,  Distance= Speed* Time

So, the distance traveled at a speed of s miles/hour for 24 hours will be:  d_(1)= (s*24)miles = 24s miles.

Now, the speed is 17 miles/hour faster for another hour. So the speed for this another hour is (s+17)miles/hour

So, the distance traveled in this another hour =[(s+17)*1]miles = (s+17) miles

Thus, the total distance =[24s+(s+17)] miles = (25s+17) miles
