A cyclist rides at an average speed of 18 miles per hour. if she wants to bike 212km, how long in hours must she ride?
What I have so far..
212km(10^3 miles
18 mph = 28.9682 km per hour
212/28.9682 = _______ hours
7.32 Hours
To convert kilometers to miles, you need to multiply by the conversion factor of 0.621371. So, we have:
212 km x 0.621371 miles/km = 131.947892 miles
Now, we can find the time it takes to ride this distance by using the formula:
Time = Distance / Speed
Let's substitute the values:
Time = 131.947892 miles / 18 miles/hour
Now, we can divide to calculate the time:
Time = 7.33 hours
Therefore, the cyclist must ride for approximately 7.33 hours to cover a distance of 212 km at an average speed of 18 miles per hour.
To find the time it takes for the cyclist to ride 212 km, you can use the formula:
Time = Distance / Speed
Given that the average speed is 18 miles per hour, we need to convert the distance from kilometers to miles.
1 kilometer is equal to approximately 0.621371 miles.
So, 212 km is approximately 131.731292 miles (212 * 0.621371).
Now, you can plug in the values into the formula:
Time = 131.731292 miles / 18 miles per hour
Dividing, we get:
Time ≈ 7.318 hours
Therefore, the cyclist must ride for approximately 7.318 hours to cover the distance of 212 km.
