i dont remeber the exact answer but with the millions get rid of the 0s to add easier

Step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
