How fast is the train going if it can travel 100 miles in 30 minutes?

Mathematics
1 answer:
DerKrebs [107]2 years ago
4 0

30 min = 30/60 hr = 0.5 hr

d = rt

100 = r*0.5

100/0.5 = r

200 = r

r = 200 mph.

We know that Rate = distance/time

(30 minutes is .5 hour)

Rate=100 mile/.5 hour

Divide and we get:

Rate=200 MPH

(Hint: MPH is Miles per Hour---Per means "for each")

Make sense?

If f(x)=| x-2 |, then find f(-3)
GenaCL600 [577]

The value of f(-3) is 5.

In order to find this answer, we are going to input -3 in for x (this is what the notation f(-3) means).

f(x)=| x-2 |

f(-3)=| -3 -2 |

f(-3)=| -5 |

Now we have to take the absolute value.

f(-3) = 5
