Question

A certain hurricane travels at 20.88 kilometers per hour. The distance from Cuba to Key West is 145 kilometers. Write and solve a multiplication equation to find about how long it would take the hurricane to travel from Cuba to Key West. (I'm seriously stumped here, the back of the book can't even help me understand what it's asking)

Answer 1

To find out how long it takes the hurricane to travel from Cuba to Key West, divide the distance (145 km) by the hurricane's speed (20.88 km/h), which results in approximately 6.95 hours. Basically, it would take about 7 hours for the hurricane to complete the journey.

Step-by-step explanation:

The question is asking how long it would take a hurricane moving at 20.88 kilometers per hour to travel a distance of 145 kilometers from Cuba to Key West. To solve this, we can set up a multiplication equation based on the formula: Speed equals distance divided by time (s = d/t). However, we need to rearrange this formula to solve for time (t = d/s).

We can calculate the time it takes for the hurricane using the rearranged formula:

1. Divide the distance (145 km) by the hurricane's speed (20.88 km/h).
2. Calculate the result to find the time in hours.

Therefore, the equation would be: t = 145 km / 20.88 km/h.

Performing the division, we get approximately 6.95 hours.

This calculation shows that it would take about 7 hours for the hurricane to travel from Cuba to Key West.

Answer 2

v = 20.88 km / h ( velocity )
d = 145 km ( distance )
Velocity formula: v = d / t
t = d / v ( time )
t = 145 km : 20.88 km/h
t = 6.94444 h
We have to multiply 0.94444 by 60 minutes.
0.94444 · 60 = 56.67 ≈ 56 minutes 40 seconds
Answer: It would take 6 hours 56 minutes and 40 seconds.
