Question

it is 170 miles form bruce's house to the city where his brother lives. On his last trip to visit his brother, he drove for 2 hours at 55 miles per hour. Then he came to some very bad roas construction. the rest of the trip took 2 hours. how many miles per hour did bruce drive for the rest of the trip

Answer 1

This is pretty simple by the way.

Hint: For the first two hours, he drove a distance of 2(55) = 110 miles

Answer 2

170 miles - 110 miles leaves 60 miles while driving under construction.

Answer 3

So if he drove 60 miles in 2 hrs, then he must have been driving 30 mph while under construction.

Answer 4

Which makes sense because usually when driving under construction, that is the usual speed.

Answer 5

thank you soo much!(:
