Question

In the number line a dog starts at 20 and jumps 5 times and reaches 0. What is the length of each hop he made?

• A. 0
• B. 4
• C. 5
• D. 3

Answer 1

The correct option is B 4

Given,
Starting Point = 20 = Dividend
Number of hops = 5 = Divisor
Reaching Point = 0 = Remainder

Now, we have to find the lenght of
length of each hop = x = Quotient

Let's reframe the division expression using the above information.
$\frac{Dividend}{Divisor}=Quotient=\frac{20}{5}=4$

Thus, the length of each hop, Quotient = 4

Let's verify it using the number line
4 (the quotient) is repeatedly subtracted from 20 to get the remainder as zero.

Here, we started from 20 and made 5 hops of 4 to the left (in the negative direction) to reach 0 on the number line.
Hence, 4 is subtracted from 20, 5 times.

Dog jumped 5 times of 4 unit each
