Select the correct answer. adam's father drove his car at a speed of 65.2 miles per hour to go to a business conference. if his trip took 1.8 hours, how many miles did he drive? a. 113.28 miles b. 117.36 miles c. 118.92 miles d. 201.47 miles

Hence B). 117.36 miles

Step-by-step explanation:

The speed distance and time formula is given as under

Distance = Speed x time

Here we are given that

Speed = 65.20 mph

Time = 1.8 hours

we are asked to determine the distance traveled

Replacing those values in the formula we get

Distance = 65.20 x 1.8

Distance = 117.36 Miles

Hence Adam's father traveled 117.36 miles in 1.8 hours at the speed of 65.20 miles

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
