Answer:
7.2
Step-by-step explanation:
1. Natalie needed 40 minutes to get to school. In hours 40 minutes is 40/60= 2/3 hour (because there are 60 minutes in an hour). so her speed is 14.4/(2/3)= 14.4*3/2= 21.6 mph.
2. Britany needed 40+20= 60 min. 60 min= 1 hour. so she needed 1 hour her speed is 14,4/1= 14.4mph
3. The difference 21.6-14.4=7.2 is the answer .
Multiply the top and bottom by 2
6/14 = 12/28
now solving for the 2nd part is more difficult i would use cross multiply and divide . Multiply 6 and 12 which equals 72 then divide by 14 which will get you 5.142857 or 5 36/7= 71/14
