Answer 1

▶Answer :

• 80 km/hr

▶Explanation :

▶Given :

• A car covers a distance in 40 minutes in every speed of 60 km per hour.

▶To Find :

• the speed to cover the same distance on 30 minutes ?

▶Formula Used :

• Distance = speed × time

▶Solution :

A/Q

Time = 40 min

speed = 60/hr

Converting 40 min into hours :

Hence,

Time = 2/3 hrs

• Distance = Speed × Time

Distance = 60 × 2/3

Distance = 40 km

A/Q

Time = 30 minutes

Converting 30 minutes into hours :

Hence,

Time = 30/60 hrs or 0.5 hrs

• Speed = Distance / Time

Speed = 40 / 0.5

▶Speed = 80 km/hr
