Question

Mr. Anderson drove 168 miles in 3 1/2 hours. He then drove the next 2 1/4 hours at a rate of 5 miles per hour faster than the first rate. How many miles did Mr. Anderson drive during the 5 3/4 hour road trip? Enter answer as a mixed number with a proper simplified fraction.

Answer 1

168 miles/3.5 hours = 48 mph

2.25 hours(53 mph) = 119.25 miles

168 + 119.25 = 287.25 miles

= 287 1/4 miles
