On Wednesday, she drove to work and averaged 60 kilometres per hour.

On Thursday, she took the bus which averaged 15 kilometres per hour.

What was the extra time of the bus journey, in minutes, compared to when she drove on Wednesday?

Time on Wednesday = 1560\dfrac{15}{60}
= 0.25 hour
= 15 minutes

Time on Thursday = 1515\dfrac{15}{15}
= 1 hour
= 60 minutes
