If Andy drove 84 miles in 1 hour 45 minutes, how many miles can he drive in 5 hours

Andy can drive 240 miles in 5 hours.

Step-by-step explanation:

To find the answer of this, we need to first find out how many miles he can drive in just 15 minutes.

There are 7 fifteen minutes, so, 84 divided by 7 is 12.

Now we know that each 15 minutes he can drive 12 miles.

In one hour, there are 4 fifteen minutes, so 12 x 4 is 48.

Now multiply this by 5 since there is going to be 5 hours.

Easiest way to do this is 4 x 5, 20, add a zero from the 40 that we converted into a 4. So we have 200.

Now just multiply 8 by 5. 8 x 5 = 40. 200 + 40 = 240. So Andy can drive 240 miles in 5 hours.

the correct answer is the section c

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
