A cyclist bikes 3.75 miles in 0.3 hours, at that rate how many hours will it take to bike 4.5 miles?

Question

SOMEONE HELPPPP THIS IS SO HARD FOR SOME REASON, I THOUGHT I GOT IT BUT IT'S WRONGGGGGGGGGG :( 😭😭😭😭😭😭

Answer 1

3.75 miles .3 hours

4.5 in how many hours

x/4.5 = .3/3.75

x = 4.5(.3)/3.75 = 1.35/3.75 = .36 hours to go 4.5 miles

the ratio of hours to miles is a constant

.35 hours= .36 times 60 minutes = 21 minutes and 36 seconds
