Question

Am I correct? I don’t think I am, please explain how i can get the right answer if I got it wrong, thank you!

Answer 1

Answer:

that's wrong, its 217 1/2 miles

Step-by-step explanation:

3/4 of a minute is 45 seconds

the easiest way to this is you figure there is 15 intervals of 3 seconds in 45 seconds so do 15 times 14.5 and get 217 1/2 miles

Answer 2

Answer:

72 1/2

I THINK THIS IS THE ANWER

Step-by-step explanation:

Firstly convert 3/4 of a minute to seconds

3/4 of a min= 15 seconds

the questions is basically saying this:

14 1/2 in 3 seconds then how much in 15 seconds

so we have to get from 3 seconds to 15 seconds and to do that we need to see how much we need to multiply from 3 seconds to 15 seconds

15/3= 5

we need to multiply by 5

so if we have to multiply 3 to get to 15

then we also need to multiply 14 1/2 by 5 because we want to know how far it can travel in 15 seconds and to do that we need to multiply 14 1/2 by 5.

and that gives us the answer of 72 1/2
