168/84 = ______ hours
thank you! so much and my middle name is sue
You're welcome. And we share a great name! :-)
To find out how long Mary will take to travel a distance of 168 kilometers, we can use the formula for speed:
Speed = Distance / Time
Given that Mary drives at a constant speed of 84 km/h and the distance she needs to travel is 168 kilometers, we can rearrange the formula to solve for time:
Time = Distance / Speed
Plugging in the values, we have:
Time = 168 km / 84 km/h
Simplifying, we find:
Time = 2 hours
Therefore, Mary will take 2 hours to travel a distance of 168 kilometers.
