Angelo’s kayak travels 10 km/h in still water. If the rivers current flows at a rate of 3 km/h, how long will it take to travel 38 km downstream?
Need help ASAP
Well, if Angelo's kayak travels at 10 km/h in still water, we need to take into account the river's current. So, if the current flows at a rate of 3 km/h downstream, that means the kayak's effective speed will be 10 km/h + 3 km/h = 13 km/h.
To find out how long it will take to travel 38 km downstream, we can use the formula Time = Distance / Speed. Therefore, the time it will take is:
Time = 38 km / 13 km/h
So, let me grab a calculator real quick... *clownishly rummages through pockets* Ah, here it is! Okay, let's do some math!
38 km divided by 13 km/h equals approximately 2.923 hours.
So, it will take Angelo's kayak approximately 2.923 hours to travel 38 km downstream. Happy kayaking!
To determine the time it will take for Angelo to travel downstream, we need to first calculate the effective speed of the kayak when aided by the river's current.
The effective speed downstream can be found by adding the speed of the kayak in still water to the speed of the river's current:
Effective speed downstream = Kayak's speed in still water + River's current speed
= 10 km/h + 3 km/h
= 13 km/h
Given that Angelo needs to travel 38 km downstream, we can calculate the time it will take using the formula:
Time = Distance / Speed
Time = 38 km / 13 km/h
Calculating this:
Time = 2.923 hours
Therefore, it will take approximately 2.923 hours (or 2 hours and 55 minutes) for Angelo to travel 38 km downstream.
Sure! To find out how long it will take Angelo's kayak to travel 38 km downstream, we need to consider the speed of the kayak in still water and the speed of the river's current.
When traveling downstream, the speed of the kayak is increased by the speed of the current. In this case, Angelo's kayak travels at 10 km/h in still water, and the river's current flows at a rate of 3 km/h. Therefore, the effective speed of the kayak downstream is 10 km/h (speed in still water) + 3 km/h (speed of the current) = 13 km/h.
To calculate the time it takes, we can use the formula:
Time = Distance / Speed
In this case, the distance is 38 km (given in the question) and the speed is 13 km/h (effective speed downstream). So, the calculation would be:
Time = 38 km / 13 km/h ≈ 2.92 hours
Therefore, it will take approximately 2.92 hours or 2 hours and 55 minutes for Angelo's kayak to travel 38 km downstream.
the downstream speed is 10+3 = 13 km/hr
now, since time = distance/speed, ...
