Question

panchito and johnny live 83 miles apart and travel towards each other, but johnny leaves 15 minutes later if panchito drives at 45 mph and johnny drives at 60 mph how long (in minutes) after johnny leaves will it take them to meet?

Answer 1

Panchito travels for 1/4 (0.25) hour more

(45)(t + 0.25) + (60)(t) = 83

Can you solve for t and answer? Note: t is in hours and the request is for minutes
