Atruck traveling at an average rate of 45 miles per hour leaves a rest stop. fifteen minutes later a car traveling at an average rate of 60 miles per hour leaves the same rest stop traveling the same route. how long will it take for the car to catch up with the truck? a. 15 minutes b. 45 minutes c. 3 hours d. 1 hour 15 minutes

D. 1 hour and 15 minutes

Step-by-step explanation:

45(1/4)=15

Let t = Time of stopwatch when the car catches the Truck

Let d = distance the car travels until the car catches the truck

d-15=45t

d=60t

60t - 15=45t

15t = 15

t=1

d - 15 = 45(1)

d = 60

and,

d =60(1)

d =60

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
