To calculate the time it will take, take the distance between Memphis and New Orleans and divide it by the speed at which the train is traveling: 395.1 / 79
The answer you will get is 5.001
We'll probably need a photo of the problem if possible.
From the first two inference, it takes her phone 1 minute to charge 2% i.e 1 minute of charge = 2% of battery.
Therefore; charging from scratch,
1 min = 2%
x mins = 50%.
using cross multiplication,
x mins = (50% × 1 min) ÷ 2%.
x = 25 mins.
For 90%, applying the same formula,
y min = (90% × 1 min) ÷ 2%
y = 45 mins.
So from zero percent, it will take Dana's phone 25 minutes to charge to 50% and 45 minutes to charge to 90%.

17.4% = 0.174
so retail price = 8,350 + 8,350 * 0.174
= $9802.90
