The question was too long so its in the description *sorry about that*.

Question

Mr. Anderson drove 168 miles in 3 and one-half hours. He then drove the next 2 and one-fourth hours at a rate of 5 miles an hour faster than the first rate. How many miles did Mr. Anderson drive during the 5 and three-fourth hours? SHOW YOUR WORK

Answer 1

The basic underlying formula to be used is d = rt (distance = rate x time).

 

1. Use the first sentence and the formula to calculate the rate for the first leg of the trip.
2. Use the rate found in step 1 and the information about the rate for the second leg of the trip (see the second sentence) to calculate the rate for the second leg of the trip.
3. Use the rate calculated in step 2 and the time for the second leg of the trip to calculate the distance traveled for the second leg of the trip. (Use the distance formula again.)
4. Add the distances for the two legs to calculate the final answer to the question (287.25 miles).
