In the morning Maria drove to a buisness appointment at 80 mph. her speed on return in the afternoon was 70mph. the return trip took 1/7 hr longer because of heavy traffic. how far did she travel
Answer provided by our tutors
let
t = the time of Marias travel to a business appointment
t + 1/7 the return trip took 1/7 hr longer because of heavy traffic
since speed = distance/time => distance = speed*time
80*t = 70(t + 1/7)
by solving we find
t = 1 hours
