A cyclist rides at an average speed of 30 .If she wants to bike 189 , how long (in hours) must she ride?
30 what? 189?
30 mph, 189km
To find the time (in hours) it takes for the cyclist to bike 189 miles, we can use the formula:
Time = Distance / Speed
In this case, the distance is 189 miles and the speed is 30 miles per hour.
Therefore, we have:
Time = 189 miles / 30 miles per hour
To simplify the calculation, we can divide 189 by 30:
Time ≈ 6.3 hours
So, the cyclist must ride for approximately 6.3 hours to cover a distance of 189 miles.
