Question 97223
You ride in a train for 175 miles at an average speed of 50 miles and hour how many hours is the trip?

Formula is r*t = d   where r is the rate of speed, t is time, and d is distance.

You know the rate is 50, but you don't know time, and distance is 175, so your equation is 50t = 175.  

To solve, divide each side by 50 and simplify.

50t/50 = 175/50 

t = 3.5 hours
