A cyclist bikes at a constant speed for 25 miles. He then returns home at the same speed but takes a different route. His return trip takes 1 hour longer and is 30 miles. Find his speed?
Let speed be S
Then time on outbound trip =
Time taken on return trip =
Time equation formed:
25 = 30 – S ------- Multiplying by LCD, S
S, or speed = 30 – 25, or mph
