The peterson's drove 562.5 miles in 12.3 hours. the castillo's drove 353.6 miles in 8 hours. on average, who was driving at a faster speed? explain your reasoning

Set up 2 proportions

562.5 over 12.3 = x over 1

and

353.6 over 8 = x over 1

then cross multiply both of them

12.3x = 562.5

and

8x = 353.6

then divide both of them

round
x = 45.73

and

x = 44.2

based on those answers the petersons were driving faster
