Question

Olivia left a 1:54 to visit her grandma's house. She arrived at 4:57 after driving fifty mph. On the way home, Olivia drove fifty-three mph. How long will it take Olivia to drive home? (I would appreciate the full solution)

Answer 1

answer is 172.6 min as

V1 = d/T1 ( it is vel to drive to grandma )

and V2 = d/ T2 ( it is vel to drive home )

V1/V2 = T2/T1 so after solving it you will get answer

put time and vel as you wish but put both vel as same unit and the unit you use in T1 answer will be on that unit
