Kiran read for x minutes, and Andre read for 5/8 more than that. Write an equation that relates the number of minutes Kiran read

Liula [17]

Answer: $y = 1.625 x$

Step-by-step explanation:

Here x represents the time taken by Kiran in reading (in minutes) and y represents the time taken by Andrew in reading (in minutes).

According to the question,

Andre read for 5/8 more than kiran.

Thus, The time taken by Andrew(in minutes) = time taken by kiran + 5/8 of time taken by kiran

= $x + \frac{5}{8}\times x$

= $\frac{8}{8} + \frac{5}{8}$

= $\frac{13x}{8}$

= $1.625 x$

Thus, required equation,

$y = 1.625 x$
