Answers
Answer:
Hazel 5 hours to run 46.25 km at an average speed of 9.25 km/hour.
Step-by-step explanation:
We can use the formula:
time = distance/speed
to calculate the time it will take Hazel to run 46.25 km at an average speed of 9.25 km/hour.
Substituting the given values into the formula, we get:
time = 46.25 km / 9.25 km/hour
Simplifying the expression on the right-hand side, we get:
time = 5 hours
Therefore, it will take Hazel 5 hours to run 46.25 km at an average speed of 9.25 km/hour.
Explanation:
The formula time = distance/speed relates the time taken to cover a certain distance at a given speed. In this case, we know the distance (46.25 km) and the speed (9.25 km/hour), so we can use the formula to calculate the time taken.
We divide the distance (46.25 km) by the speed (9.25 km/hour) to get the time taken (in hours). The units of kilometers cancel out, leaving only the unit of hours, which is the desired unit for time. The resulting value of 5 hours means that it will take Hazel 5 hours to run 46.25 km at an average speed of 9.25 km/hour.
