Tju [1.3M]

The time take for the cyclist to travel from Fort Worth to Fresno is $90 \ hours$

Explanation:

It is given that the distance from Fort Worth to Fresno is 1,530 miles.

The average speed of the cyclist is 17 miles per hour.

The time travelled by the cyclist can be determined using the formula,

$Distance=Speed \times Time$

Substituting the value of distance and speed, we get,

$1530=17\times Time$

Dividing both sides by 17, we get,

$90 =Time$

Thus, the time take for the cyclist to travel from Fort Worth to Fresno is $90 \ hours$

Answer:

Step-by-step explanation:

As per the given question,

In a manufacturing operation, a part is produced by machining, polishing, and painting.

Number of machine tools = 3

Number of polishing tools = 4

Number of painting tools = 3

Now,

For finding the different routing consisting of machining, followed by polishing, and followed by painting, we have to simply multiply the number of machine tools, polishing tools and painting tools.

Therefore,

The different routing (consisting of machining, followed by polishing, and followed by painting) for a part are possible = 3 × 4 × 3 = 36.

Hence, the required answer is 36.
