Question

lydia went on a trip with her family. for three hours they drove east and drove 40 miles per hour. then, they drove north for one hour and drove 50 miles. how far was lydia and her family from their home after 4 hours

Answer 1

170 miles

Explanation:

first, for 3 hours they drove 40 mph. this means you have to multiply 40 mph by the 3 hours.

40*3=120

then you have to add the extra 50 miles that they drive north because their speed changed.

120+50=170
