Answer:

D. Jacob rode a 45-kilometer race in 3 hours.

Step-by-step explanation:

1h = 15km

A. : 30m = [tex]\frac{30}{60}[/tex] × 15km

              = 7.5km (not 2km)

B. : 15m = [tex]\frac{15}{60}[/tex] × 15km

             = 3.75km (not 4km)

C. : 5h = 5 × 15km

             = 75km (not 20km)

D. : 3h = 3 × 15km

             = 45km (Yep, 45km)
