Solution

The correct option is B Car
Adam's bike covers distance =10 miles
and Time taken to cover that distance =30 minutes
Driving speed of bike=Distance coveredTime taken
=1030
=0.33 miles/minute
His car covers the same distance of 10 miles
and Time taken =20 minutes
Now,
Driving speed of car=Distance coveredTime taken
=1020
=0.5 miles/minute
Since, 0.5>0.33.
Driving speed of car>Driving speed of bike
This means Adam's car is faster then his bike.
