Comparing Nathan's rate for the two days, Nathan's speed(rate)/was faster today than yesterday

Step-by-step explanation:

Yesterday Nathan rode his bike 39 kilometers in 3 hours.

Today Nathan rode his bike 8 kilometers in 30 minutes. Compare his rates for those two days. Show your work.

Speed /rate =>Distance(km)/ Time(hr)

For yesterday

Speed = 39km/3 hour

Speed = 13 km/hr

For Today

Convert time in minutes to hour

60 minutes = 1 hour

30 minutes = x hour

= 30/60

= 0.5 hour

Speed=> 8km/ 0.5 hour

=16 km/hr

Comparing Nathan's rate for the two days, Nathan's speed(rate)/was faster today than yesterday
