D stands for distance

S stands for speed

T stands for time

Step-by-step explanation:

Distance= 12miles

Speed= 8miles per hour

Adam

Speed= 6miles per hour

Distance= 12miles

Time= distance divided by speed

= 12miles divided by 6miles per hour

=2hours or 120minutes

120minutes - 90minutes=30 minutes
