How long does it take for a bicyclist to travel 90 miles at the rate of 18 miles per hour

5 hours

Step-by-step explanation:

We are given that a bicyclist travels for 90 miles at the rate of 18 miles per hour and we are to find the time he took to complete this journey.

We will use the speed - distance formula here to find the time:

Time = Distance / speed

So substituting the given values in the above formula:

Time = 90 / 18 = 5 hours

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
