Contestants in the Run-and-Bike-a-thon run for a specified length of time, then bike for a specified length of time. Jason ran at an average speed of 5.2 mi/h and biked at an average speed of 20.2 mi/h, going a
total of 14.6 miles. Seth ran at an average speed of 10.4 mi/h and biked at an average speed of 18.8 mi/h,
going a total of 17.8 miles. For how long do contestants run and for how long do they bike? Round to the
nearest hundredth if nessnecessarilynecessary.
Contestants run hour and bike I hour.

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer:

probably the same as it is today since you did not eat the corn dogs yet

step-by-step explanation:

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
