Driving at the speed limit, it takes you 2 hours to drive your delivery truck 100 miles. assuming you drive at the same speed, how many hours will it take you to drive 300 miles

Speed is the rate of change of distance.

the speed of the truck for the 100 miles within 2 hours is

speed = 100 miles travelled / 2 hours taken

speed = 50 miles/hour

assuming that the driver drives at 50 miles/hr

the time taken to drive 50 miles is - 1 hour

therefore to drive 300 miles - it takes - 300 miles / 50 miles/hr

the time taken is - 6 hours

it takes 6 hours to drive for 300 miles
