Randy drove 540 miles in three times the time it took andy to travel 135 miles andy’s speed was slower than randy’s by 15 miles per hour what were the rate and time of each? i really need !

Let's assume

Randy's speed =x mph

we have

Andy’s speed was slower than Randy’s by 15 miles per hour

so,

Andy's speed =x-15

Randy drove 540 miles

so, we can find time taken by Randy

time = distance / speed

so, we get

we can find time taken by Andy

time = distance / speed

so, we get

Randy drove 540 miles in three times the time it took Andy to travel 135 miles

so,

we can plug it

now, we can solve for x

so,

Calculation of rate:

Randy's speed is 60 mph

Andy's speed =x-15

Andy's speed =60-15=45mph

Calculation of time:

Randy's time is

Andy's time is

$12. that is my answer.

i think 5 miles per hour
