It took a car 6 hours to cover the distance between points a and b with the speed of 50 mph. how long will it take a bus to cover the same distance, if it travels at 40 mph?

7.5 hours//7 hours and 30 min

Step-by-step explanation:

50*6=300

since you now know that its 300 miles, you divide by 40

300/40=7.5

7.5 Hours

Step-by-step explanation:

A--->B was 6 hrs at 50 mph so 6*50=300

(50 miles PER HOUR, and there are 6 hrs.)

So if you are trying to figure out how long it would take if travelling at 40mph, divide 300 by 40 and get 7.5 hrs

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.
