Jason's mom drove at 100km/hr for a 160km trip.how much longer would the trip have taken if she had driven at 90km/hr

kondor19780726 [428]

We use the formule: t=S/v. So:
+ t1= 160/100 = 8/5 hrs = 5760''
+ t2= 160/90 = 16/9 hrs = 6400''

=> t2-t1= 6400 - 5760 = 640'' = 10'40''

Jason jogged 2/3 mile in 1/3 hour. What was his speed in miles per hour?

fenix001 [56]

Answer:

I honestly was having the worst time trying to solve this sorry :(, for real idk if any of these are right

i got 2 answers; 1st: ≈0.5 mph

the 2nd; 2 mph

Step-by-step explanation:

Speed = $\frac{Distance}{Time}$

2/3 miles = 3520 feet

1/3 hours = 20 minutes

------Make a proportion-----

$\frac{3520ft}{20min} = \frac{1 mi=5280 ft}{1hr = 60min}$

cross multiply------

3520 * 60 = 211200

5280 * 20 = 105600

Divide $\frac{211200}{105600}= 2$

---(this is where i got confused cuz 2 doesn't make any sense)--

If you flip them, $\frac{105600}{211200}=0.5$ which makes more sense

hope i helped :(

The first one would be 8 becuase 8 times -8 would be -64. i don’t know the second one but the last one is -82 becuase 8 plus -82 equals -90.
