Question

How long will it take to get to the island 90km from the coast in a boat that travels 30km/m?

Answer 1

The value of Time Will be

`9minutes`

Step-by-step explanation:

Greetings!!!

Given values:-

Distance (s)= 90km

Speed(V)= 30km/m

Required value:-

Time(t)= ?

Solution:-

But before that how did I know Time is required

So, from the given word problem it says "How long will it take" which means it's indicating the time period.

Firstly, recall speed-distance equation

• 
  `speed = (distance)/(time)`

Substitute known variables into the equation

• 
  `30km/m = (90km)/(t)`

Solve for time

• 
  `30km/m(t) = 90km`

divide both sides of the equation by 30km/m

`(30km</strong><strong>/</strong><strong>m(t))/(30km</strong><strong>/</strong><strong>m) = (90km)/(30km</strong><strong>/</strong><strong>m)`

divide

`t = 3m`

Hope it helps!!!

Answer 2

To find the time it will take to travel a certain distance at a certain speed, you can use the formula:

time = distance/speed

In this case, the distance is 90km and the speed is 30km/m.

So, time = 90km / 30km/m = 3m

Answer:

It will take 3 hours to get to the island 90km from the coast in a boat that travels 30km/m.
