Formula for this is as follows: probability of her passing both 0.6/0.8 - first test and this is a fraction. 0.6/0.8 0.6/0.8= divide 0.6 by 0.8=0.75 that means probability of her passing the second test is 75%
In order to solve this problem, you must create a ratio. If Bangor is 240 miles away and Javier has only 4 hours to get there, we can divide 240 by 4 which equals 60 miles per hour.
