Jeff traveled at an average speed of 65 miles per hour for 2.5 hours and then traveled at an average speed of 70 miles per hour for 1.5 hours. What was the total distance in miles that Jeff traveled during this time?

267.5 miles

Step-by-step explanation:

We start with the formula for speed:

speed = distance/time

Now we solve it for distance:

distance = speed * time

65 mph for 2.5 hours + 70 mph for 1.5 hours

distance = 65 * 2.5 + 70 * 1.5

distance = 162.5 + 105

distance = 267.5

267.5 miles
