Answer:

45 miles/hour

Step-by-step explanation:

We need the speed in miles per hour so we need to changes minutes to hours

20 minutes * 1 hour /60 minutes = 1/3 hour

Speed = distance/ time

           = 15 miles/(1/3 hour)

            =15 *3 miles/hour

            = 45 miles /hour

Write a division problem that will have a 2 digit quotient and another division problem that will have a 3 digit quotient. Expla
o-na [289]

Answer:

\frac{240}{4} =60

\frac{1800}{3} =600

Step-by-step explanation:

1.  The result should by a 2 digit number.

So, I fix a two digit number first, say 60.

Then, I multiplied it by some random integer, say 4 and got 240.

Now, 240 is my dividend and 4 is my divisor.

My division problem is:

\frac{240}{4} =60


2.  The result should be a 3 digit number.

So, I fix a three digit number first, say 600.

Then, I multiplied it by some random integer, say 3 and got 1800.

Now, 1800 is my dividend and 3 is my divisor.

My division problem is:

\frac{1800}{3} =600
