Question

John can change four tires on a car

in a half hour. How many tires can
he change in 6 hours? How many
cars is that? How long does it take
John to change one tire?

Answer 1

Answer:
In 6 hours John can change 48 car tires
That is 12 cars
It takes 7 minutes and 39 seconds to change a car tire

Step-by-step explanation:
4x12=48
48/4=12
30/4=7.5

Answer 2

Take the 4 tires he changed and multiply it by two.

In one hour he can change 8 tires

8 tires times 6 hours is 48

He changes 48 tires in 6 hours.

Divide 48 by 4 because there are at least 4 tires on a car

That gives you 12

So he changed the tires of 12 cars in 6 hours.

To find the time of one tire you would take 30 min and divide it by 4. Because it takes 30 minutes to change 4

That gives you 7.5

So 7 minutes and 30 seconds to change one tire


How many can he change in 6 hours?
4x2=8 8x6=48 tires

How many cars is that?
48 divided by 4=12

How long for one tire?

30 divided by 4= 7.5 minutes
