Question

jonathan went for a jog. every time he stops to tie his shoelaces, his jog lasts 2 1/2 minutes longer. if he stops to tie his shoelaces four times, how much longer does his jog take

Answer 1

When Jonathan stops to tie his shoelaces four times, each adding 2 1/2 minutes, his jog takes an extra 10 minutes in total.

Step-by-step explanation:

Jonathan stops to tie his shoelaces four times during his jog. Each time he stops, it adds 2 1/2 minutes to his total jog time. To find out how much longer his jog takes, we need to multiply the number of stops by the additional time per stop.

Let's calculate this step by step:

1. Convert the additional time per stop to an improper fraction, which is 5/2 minutes or 2.5 minutes.
2. Multiply the number of stops, which is 4, by the additional time per stop, which is 2.5 minutes.
3. The total additional time is 10 minutes (2.5 minutes/stop x 4 stops).

So, if Jonathan stops to tie his shoelaces four times, his jog will take an extra 10 minutes in total.

Answer 2

2.5=2 1/2
2.5*4=10
10+r=j
r=time he actually ran
j=total time of jog
