Answer:
= 15mins 18 seconds. The storm chaser van drove 13.53 miles to catch up with the storm which obviously has moved less than 0.53 miles as it was same time but multiplied below by 0.5 per minute as speed per minute is 0.5 for the storm. See right at the end the storm only moved 1.11 mile.
Step-by-step explanation:
We count in 1 minutes
54 mph = 54/60 = 0.9 miles per minute
Storm = 13 m + 1 minute is;
33/60 = 0.55 miles = 11/20
M = (16 7/10 * 9/10x) = ( 3 7/10 * 11/20y ) +13
M = 15 3/10x = ( 407/200y +13) (407/200 = y starting value +13)
M = 15 3/10x = 15 3/10 = 16 7/10x (the same as 16 7/10* 9/10 for x)
M = 15 3/10 x = 15 3/10 = 15.03
M = 16 7/10x / 9/10y (is also the same as 186/1000)
X = 185⁄1000 = 37⁄200xy x 16 7/10 (as starting value)
7/10 of 60 = 42 minutes
3/10 of 60 = 18 minutes
x = 15 mins 18 seconds.
y = 15 mins 18 seconds.
as 0.005 left over for y 3/10 was actually 15.035 gives us 0.005 of 60 can not be rounded up to a second.
However as we started with 16mins and 7/10 we can see that we multiplied by 9/10 so when we divide 16 7/10 by 9/10 we find 185⁄1000 = 37⁄200
To equal the mileage of the storm of where we multiplied 3 7/10 by 17/10
= 37/200 just the same
We added 13 miles of the storm to find each was multiplied by the larger x sum 9/10 and y was multiplied
As 35/200 + 13 =
13 37/200
37/200 of 60 = 11.1 = 11.06 minutes which is
= 15.04 % more for y as 13 + 2 mins + 06 seconds = 15.06 = 15.035
The percentage looks the same but valued different as 2 of 13 as a percentage is multiplied as 13 x 15.04% to equal the 2 of 15 miles as 15.04%.
To find how many miles we go back and see 15.035 = 15 7/200
Then we multiply this by 0.9 miles for the storm van
= 15 7/200 x 0.9 = 13.5315 = 13.53 miles
For the storm itself we can prove 0.53 increase of mileage
417/200 x 0.53 = 1.10505 = 1.11 miles. rounded up
