Answer:
Eudora ran for 30 minutes and use the jetpack for 1 hour and 30 minutes
Step-by-step explanation:
Lets call x the time she ran and y the time she was using a jetpack (in hours), we have
12x + 76y = 120
Since it took 2 hours we have that x+y = 2, hence y = 2-x. We can replace y in the equation above, obtaining
12x + 76(2-x) = 120
12x+ 152 - 76x = 120
12x-76x = 120-152
-64x = -32
x = -32/-64 = 1/2 (30 minutes)
As a result
y = 1-1/2 = 3/2 (1 hour, 30 minutes)
She ran for 30 minutes and use the jetpack for 1 hour and 30 minutes.
Answer:9 6/20
Step-by-step explanation:
add numerator and find lcf on denominator add whole number
Wouldn't that be 330 miles? Units are important.
Let d represent your distance from home. At the beginning you're 330 miles away, driving home at 55 mph (average). If x represents the number of hours you've driven, then
d(x) = 330 miles - (55 mph)x
