6. A car travels 3 hours at 50 mph. Then it slows down to 40 mph for the next 7 hours. How many miles does it travel during the 10 hours?

50/3 + 40/7
50/3 - 40/7
(3 x 50) + (7 x 40)
(7 x 40) - (3 x 50)

Answers

Answer 1

total sidtance traveled in 10 hours is 430 miles

Answer 2

The correct option is the third one, the distance is:

d = (3 x 50) + (7 x 40) = 430 miles.

That is the distance that the car travels in the 10 hours.

How many miles does it travel during the 10 hours?

We need to use the formula for distance:

distance = speed*time

Then the distance traveled in these 10 hours is:

distance = 3*50 + 7*40

distance = 430mi

Where the first value is the number of hours and the second is the speed which is used in that time interval.

With that in mind, we can see that the correct option is the third one.
