Answer 1

Answer:

A car takes 2 hours to reach a destination by travelling at 60 per hour.

Step-by-step explanation:

In this problem,first we have to find out the distance.

We know, Speed= distance/time

Distance = speed × time

Speed = 60 km per hour

Distance = ?

Time= 2 hours

Therefore, Distance = 60km per hour × 2 hour

Distance = 120 km

How long will it take while travelling at 80 km/hour?

Time=?

Distance = 120 km

Speed= 80 km per hour

Time= Distance/Speed

Time= 120 km/ 80 km per hour

Therefore, Time= 1.5 hour or 1 hour 30 minutes

Answer 2

Answer:

It would take 1 h 30 min

Step-by-step explanation:
