Explanation:
Remember that
![1\ h= 60\ min](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kjh56n2dptzo1lgm0041a1di9c4uljp3d0.png)
step 1
we know that
Kevin start his science test: 2:34 p.m (after noon)
Convert hours to minutes
![2:34 = 2*60 + 34 = 154\ min](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vyhcfklom5o1e0z96545uczq4yp0spwl3y.png)
step 2
Kevin finished the test 75 minutes later
so
step 3
Kevin has football practice at 4:15 p.m (after noon)
Convert hours to minutes
![4:15 = 4*60 + 15 =255\ min](https://img.qammunity.org/2020/formulas/mathematics/middle-school/3n49uofmn15roh94od1hurnyqtcj4wdg45.png)
step 4
Find out the time between end of test and start of football practice:
Note : The reference for both times is the same ( after noon)
![255 - 229 = 26\ min](https://img.qammunity.org/2020/formulas/mathematics/middle-school/9ix9clga9osoxf15xs5m5sq1jf33cq0gdx.png)
