Question

After school, Maya and Naomi headed to the beach, 6 miles away. Maya decided to bike while Naomi took a bus. The graph below shows their journeys, indicating the time and distance traveled. What was the difference, in miles per hour, between Naomi's and Maya's average speeds?

A 6
B 12
C 18
D 20
E 24

Answer 1

e) 24 miles per hour

Explanation:

Naomi travels 6 miles in 10 minutes

To find the speed, we need to divide DISTANCE by TIME

However, to do that, we need to change the 10 minutes into hours.

10 minutes = 1/6 of an hour

Now, 6/ 1/6 = 36 miles per hour

Maya travels 12 miles in 30 minutes

To find the speed, we need to divide DISTANCE by TIME

However, to do that, we need to change the 30 minutes into hours.

30 minutes = 1/2 of an hour

Now, 6/ 1/2 = 12 miles per hour

_________________________

36 mph - 12 mph = 24 mph
