Question

Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start of 10 meters past the starting line. Chana skated at 3 meters per second, and Josiah skated at 2 meters per second.

a) Josiah is faster than Chana.
b) Chana is faster than Josiah.
c) They have the same speed.
d) Cannot be determined.

Answer 1

Chana is faster than Josiah because she skates at a speed of 3 m/s compared to Josiah's 2 m/s.

Step-by-step explanation:

The answer to the student's question about the relative speeds of Chana and Josiah, who started skating at the same time in the same direction, is that Chana is faster than Josiah. Given that Chana skated at 3 meters per second and Josiah skated at 2 meters per second, we can determine who is faster. Since Chana's speed is 3 m/s, which is greater than Josiah's speed of 2 m/s, she can eventually catch up to him despite his 10-meter head start.
