Question

Kathryn leaves her home and travels at an average speed of 45 mi./hr. until she reaches her grandmother's home 180 mi. away. How long does it take her to reach her grandmother's house?

Answer 1

It would take Kathryn 4 hours to reach her grandmother's house.

Answer 2

The time it takes to travel a distance at a constant speed is given by the formula:

time = distance / speed

So, to find the time it takes Kathryn to reach her grandmother's house, we can use this formula:

time = 180 miles / 45 mph = 4 hours
