I'm assuming the two cars start from the same point!
<span>Let's measure time t from the time when Car 2 starts. </span>
<span>Then the distances travelled by the cars up to the time of overtaking, t, must be the same. </span>
<span>And we need to measure all time in hours, so 18 mins. is 0.3 hours. </span>
<span>So, 45 x (0.3 + t) = 65 x t, so 20t = 13.5, so t = 13.5/20 = 27/40 = 40.5/60, i.e. 40 min 30 sec</span>
Subtract 88x from both sides. This will put all x coefficients on one side of the equation, and all constants on the other side, allowing her to easily find the value of x from there.
The equation would then become
Answer:
She read 34% of the chapter
Step-by-step explanation:
You divide 17 by 50 and that gives you your answer
17/50=.34
move the decimal point 2 places to the right and the gives you your precent
.34=34%
