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.
