Pg. 61 QUESTION I chose
10. Trevor rode his mountain bike 84 km in
3 h. Jillian rode 70 km in 2.5 h. Who is
the faster cyclist? How do you know?

Neither is the faster cyclist, and here is how I know.

Trevor
84km in 3 hours
3 ÷ 3 = 1
84 ÷ 3 = 28km/hour or 28 kilometers per hour

Jillian
70km in 2.5 hours
2.5 ÷ 2.5 = 1
70 ÷ 2.5 = 28km/hour or 28 kilometers per hour
