Bill and greg are walking in opposite directions with speeds of 45 and 75 feet per minute. when they started, the distance between them was 20 feet. what will be the distance between them in 2.5 min?

The distance between them in 2.5 min will be 320 ft

Step-by-step explanation:

Let

x> Bill distance after 2.5  min > speed  45 ft/min

y> Greg distance after 2.5  min> speed 75 ft/min

z> distance between them in 2.5 min

we Know that

z=x+y+20

Remember that

To find the distance multiply the speed by the time

so

x=45*2.5=112.5 ft

y=75*2.5=187.5 ft

therefore

z=x+y+20> 112.5+187.5+20=320 ft

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
