Mr. Anderson drove 168 miles in 3.5 hours. He then drove the next 2.25 hours at a rate of 5 miles an hour faster than the first rate. How many miles did Mr. Anderson drive during the 5.75 hours?

Answers

  1. Mr. Anderson drove 168 miles in 3.5 hours. Distance here is 168 miles.
  2. He drove for 2.25 at a rate of 5miles/hour. The speed here is 5miles/hour.

Since we are looking for distance, we have to convert the 2nd part (which is the speed) to dostance.

Distance = speed x time

Distance = 5 x 2.25 = 11.25

In the first part, he drove for 3.5 hours. And in the 2nd part, he drove for 2.25 hours which sum up together to be 5.75 hours.

Since we have the distances for both parts now, we just sum it up

which it 168 + 11.25 = 179.25 miles

I hope this is good

Two circles have the same radius. Is the combined area of the two circles the same as the area of a circle with twice the radius? Explain.

Answers

ok so area=pir^2

2 circles with same area=2pir^2

circle with 2 times radius=pi(2r)^2=pi4r^2=4pir^2

is 2 circles with same area equal to circle with 2 times radius?
is 2pir^2=4pir^2?
is 2=4?
no


therfor the answer is no

it is because the radius is squaered so the doubled gets doubled makng it quadrupuled when the first one only gets doubled
