If dr. bob ride his bike to his office he averages 12 mph if he drives his car he averages 48 mph his time driving is 1/4 hour less than his time bicycling how far is his office

2.4 miles

Step-by-step explanation:

From the question;

We are going to assume the distance to the office is x miles

Therefore;

Time taken when using the bike;

Time = distance ÷ speed

         = x/12 hours

Time taken when using the car;

Time = x/48 hours

But, time taken when using the car is 1/4 hours less.

Therefore;

1/12 hours - x/48 hours = 1/4 hr

That is;

We want to solve for x.

Multiplying by LCM, 48

We get,

  5x = 12

    x = 12/5

      = 2.4 miles

Therefore, the office is 2.4 miles away.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
