Question

Marian traveled at an average speed of 65 mi/h for 15 hours. Kristen travels at an average speed of 50 mi/h. How many hours does it take kristen to travel the same distance marian traveled? express your answer as a decimal to the nearest tenth.

Answer 1

The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.

The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:

speed = distance / time

Therefore,

distance = time × speed

distance = 15 × 65

distance = 975 miles

Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:

speed = distance / time

time = distance / speed

time = 975 / 50

time = 19.5 hours
