Mary drives her car with a constant speed of 84 km/h. How long will she take to travel a distance of 168 kilometers?

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.
