A train travels 25 miles in 20 minutes. What is the train speed in miles per hour?

kenny6666 [7]

60 min = 1 hour

1st we need to know how many times 20 goes in 60 so we will divide.

60 ÷ 20 = 3

Now we will multiply to find the trains speed in miles per hour.

3 × 25 = 75

SO, the train travels 75 miles per hour.

Answer:

$34^o=1/2((3x-2)^0-(x+6)^o)$

$68^o=3x^o-2^o-x^o-6^o$

$68^o+8^o=2x^o-8+8^o$

$76^o=2x^o-->x=38^o$
