Joe and pat both cycled a distance of 27km starting at the same time.
joe completed his journey 18 minutes earlier than Pat.
Joes average speed was 18 km/h.
What was pats average speed in km/h?
:
Find Joe's travel time for the 27 km
27%2F18 = 1.5 hrs or 90 min
It took Pat an additional 18 min to complete the race or 108 min total
Convert 108 min to 1.8 hrs
Find his speed
27%2F1.8 = 15 km/hr is Pat's speed
