Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
John gets lost on his way home.  His normal trip is 150 miles and would take him 3 hours.  He ends up driving 50 miles out of the way and has to get back on track.  How long did the trip take if he kept the same speed?

### Response:
His speed is 150/3=<<150/3=50>>50 mph
His trip took 150+50+50=<<150+50+50=250>>250 miles
So it took 250/50=<<250/50=5>>5 hours
