For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 105 miles in 3 hours, how long does
it take to travel 140 miles?

Respuesta :

Answer:  4 hours

====================================================

Explanation:

We'll use the first two values to find the speed of the car

speed = distance/time = (105 miles)/(3 hours) = 35 mph

Then use this to find how long it takes to drive 140 miles

time = distance/speed = (140 miles)/(35 mph) = 4 hours

Answer:

4 hours
