If $a=7$ and $b=13$, what is the number of even positive integers less than $ab$?
Paladinen [302]

The number of even positive integers less than a.b, i.e 90, is 45.

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtract, divide, and multiplying built-in functions.

Given that
a = 7 and b = 13

⇒ ab

Substitute the values of a and b in the above expression,

⇒ (7)(13)

⇒ 91

Since the number of even positive integers is less than

⇒ ab > even positive

⇒ 90 > even positive

since the even number less than a.b i.e. 91 is 90,
Here, 90 is the 45th number in the series of even positive numbers.


Thus, the number of even positive integer less than a.b, i.e 90, is 45

There are two simultaneous equations . Remeber that v=d/t, 1hour = 60 minutes.

1. 40 = (d+15)/(t+0.5)

2. 50 = d/t

solving: d= 25 miles and t=0.5 hours.

The distance traveled is:

D=d+d+15
